Thorlabs' fiber-based, compact, Czerny-Turner spectrometers are available in three models. Two are sub-nanometer accuracy models that provide detection in the 350 - 700 nm or 500 - 1000 nm range. A third model offers a wide 200 - 1000 nm spectral range with better than 2 nm accuracy. With a footprint that measures roughly the size of a portable hard drive (122 mm x 79 mm x 29.5 mm), the performance of these spectrometers is ideal for educational applications or fiber-based systems. Each unit comes amplitude corrected and is shipped with a calibration report.

Although small, the unit shares features with larger, more expensive spectrometers such as the ability to be synchronized via a TTL trigger input (up to 100 Hz) and to automatically compensate for noise created by dark current. The three models share the same design with the CCD chips, gratings, and lenses being optimized for the specified wavelength range.

Each spectrometer ships with a software CD-ROM, an SMB-to-BNC adapter cable for external trigger signals, a 1.5 m high-speed USB cable, and a fiber optic patch cable with SMA905 connectors. The CCS100 and CCS175 include our M14L01 patch cable, which is 1 m long and has a Ø50 µm core, while the CCS200 includes a 1 m long patch cable built with our FG200UCC optical fiber, which has a Ø200 µm core. All units are factory-calibrated by Thorlabs prior to shipment. Recalibration can be easily performed by the user at any point.

Note: A glass window in front of the CCD causes etalon effects which vary from unit to unit. If you require more information to determine if these spectrometers are suitable for your application, please contact technical support.

Mounting Options
For ease and stability of mounting, our compact CCD spectrometers are each equipped with two bottom-located taps separated by 1" (25.4 mm). The imperial versions feature 1/4"-20 taps, while the metric versions are equipped with M6 taps.

Software Package for the CCD Spectrometers
The spectrometer comes with a software package that has a graphical user interface (GUI) and an extensive set of drivers (C/C++, LabWindows/CVI, Dot NET, NI LabVIEWa, and Visual Basic). The GUI can display the spectra, background, and peaks in a single window if desired. Additionally, diverse algorithms can be applied for smoothing, averaging, or calculating absorption and transmission. The measurement results can be compared with other stored profiles. The included drivers allow for complete functional control of the Czerny-Turner Spectrometers featured here, allowing the user to design his or her own interface software or to integrate the unit with a test and measurement setup for automated testing. Please see the User Interface tab for more details. The link to download the software can be found on the Software tab. This software package is also designed to operate our optical spectrum analyzers.

Cosine Correctors
Thorlabs cosine correctors (available below) are designed to mate with either an SMA connectorized fiber or the input port of a CCS spectrometer. They feature diffusers at the input apertures and allow the CCS spectrometers to be used for free-space measurements.

Fiber Bundles
In addition to the SMA to SMA cable included with each spectrometer (detailed above), Thorlabs offers linear-to-round fiber bundles, which are sold below. These bundles are optimized for use with spectrometers and have a linear fiber array on the spectrometer side of the cable, which matches the geometry of the spectrometer slit. This provides higher signal levels in the spectrometer. Please note that while these bundles increase signal strength, a single small-core fiber should be used to maintain full spectral precision of the high-accuracy spectrometers.

Thorlabs also offers a large selection of alternative fiber optic patch cables and bundles that may be purchased separately. For example, the M16L01 is an SMA-to-FC/PC-connectorized cable that contains the same fiber as the M14L01 patch cable included with our CCS100 and CCS175 spectrometers. Our reflection probe fiber bundles are a single-cable solution that connects to the spectrometer, light source, and sample for reflection spectroscopy applications (see the Application tab for details). We also offer custom patch cables, which can be ordered here.

  • The software package supports LabVIEW from version 8.5 onwards. For earlier versions the code can be converted. Please contact Technical Support for details.

Peakfinder Screen

The CCS Series Spectrometers feature the easy-to-use OSA software with a graphical user interface. The package is designed for laboratory and manufacturing applications. The data, background, and peaks can be shown in a single graph. With the help of smoothing and averaging algorithms the user is able to enhance specific features of the spectra. Furthermore the software is able to handle several devices at one time which are presented in a single graph.

The above screenshot shows the Peak Track analysis mode, which allows the position, amplitude, and width of peaks in the spectrum to be tracked over time. As long as track peak mode is active, the track peak analysis area will be displayed below the graph. A table with information on each peak is to the lower right while the lower left of the screen contains a small toolbox used to set the criteria for identifying the peaks.

Additionally, Thorlabs provides drivers for C/C++, LabWindows/CVI, Dot NET, NI LabVIEW, and Visual Basic for more specific demands. The software package supports NI LabVIEW from version 8.5 onwards. For earlier versions the code can be converted. Please contact for details.

Reflection Spectroscopy Application

These CCD spectrometers can be used along with our reflection spectroscopy probes, broadband fiber-coupled light sources, and fiber probe holders to take diffuse reflection, specular reflection, and color measurements.

Reflection Spectroscopy Fiber Probe Bundle

Thorlabs offers several CCD-based spectrometers for use in the visible, NIR, or UV to NIR spectral ranges. The CCS100 and CCS175 operate in the 350 - 700 nm and 500 - 1000 nm spectral ranges with 0.5 nm and 0.6 nm resolution, respectively. The extended-range CCS200 operates in the 200 - 1000 nm spectral range with 2.0 nm resolution.

Light Sources
The SLS201L tungsten-halogen broadband fiber-coupled light source, sold below, delivers a 2796 K blackbody-type spectrum in the 360 - 2600 nm wavelength range and has active electronic stabilization for low spectral and intensity drift. Alternatively, the SLS202L light source delivers similar performance with a 1900 K color temperature and 450 - 5500 nm emission range, while the SLS203L provides free space output with a 1500 K temperature and 500 - 9000 nm emission range. We also offer fiber-coupled LEDs available with a selection of peak wavelengths or a broadband white-light emission spectra.

Alternatively, if the reflection probe is not used for illumination, Thorlabs offers a wide range of broadband and single wavelength light sources that are free-space or operate with a single fiber cable output. Our liquid light guide-coupled plasma light sources offer extremely intense illumination with a blackbody-type emission spectrum. Our line of fiber-coupled laser sources offers a selection of options for intense single-wavelength illumination.

Diffuse Reflection Holder

Reflection Probe Fiber Bundles
Thorlabs offers reflection probes with either high-OH or low-OH multimode fiber for wavelengths from 250 - 1200 nm and 400 - 2400 nm, respectively. Probes are available with a sample end that terminates in either a Ø1/4" probe or an SMA905 connector. We also offer Ø1/4" and SMA-terminated probes with linear fiber bundle spectrometer ends that provide increased spectrometer coupling efficiency for samples with low reflectance.

If the coaxial illumination provided by a reflection probe bundle is not critical, separate fiber patch cables or bundles with SMA connectors can be used for illumination and signal collection. Our large-core round bundles maximize illumination intensity, while our single-fiber multimode SMA patch cables are useful for precise illumination, or for connection to a fiber-coupled laser. We also offer round-to-linear fiber bundles, which maximize signal strength at the spectrometer.

Reflection Probe Holders
Thorlabs offers the RPS and RPS-SMA fiber probe stands (RPS-SMA shown above and to the right), which allow for precise, stable positioning of the fiber optic probe at an angle of 90° or 45° relative to the sample. The probe holder arms (also sold separately) can also be integrated into other optomechanical setups using Ø1/2" posts. Alternatively, the RPH and RPH-SMA probe holder blocks sit directly on a sample, allowing the fiber tip to be positioned close to the surface and also blocking out room lights from the area under test.

Linear Fiber Bundles vs. Single-Fiber Patch Cables

Entrance Slit Throughput Comparison
Our linear fiber bundles (sold below) can be used in place of the single-fiber patch cables included with these spectrometers to provide a significant increase in signal strength. The images below show how light exiting a linear fiber bundle more closely matches the geometry of the spectrometer's entrance slit than that from a standard patch cable. The accompanying graphs show comparison spectra of an SLS201L broadband light source measured with a CCS100 spectrometer when using a linear bundle versus a standard patch cable. As shown in the graphs below, the Ø105 µm core linear bundles provide a maximum power increase of ~500% versus a comparable single-fiber cable, while the Ø200 µm core linear bundles provide a maximum power increase of ~300%.

Hi, I am currently using the CCS 100 spectrometer with integration sphere for measuring PLQE. I have checked the intensity correction. What is the unit after correction? Is it possible to get the spectral irradiance in mW*m-2*nm-1? Or other relative way to these measurement purpose? Thank you very much!
Posted Date:2016-12-28 05:02:21.0
This is a response from Wolfgang at Thorlabs. Thank you for your inquiry. The amplitude correction feature in the software will take the wavelength dependent responsivity of the CCS spectrometer into account. This way e.g. peaks at different wavelengths can be compared relative to each other. The spectrum is however still in arbitrary units and not absolutely calibrated. Unfortunately, it is not possible to measure absolute optical powers with the CCS spectrometers. I have contacted you directly to provide further assistance.
Posted Date:2016-12-12 04:05:32.357
I would like to measure the wavelength (nm) and power (mW*m-2*nm-1) of a led lamp. Is the spectrometer can measue both or I need to buy a power meter for power measurement?
Posted Date:2016-12-12 04:37:57.0
This is a response from Sebastian at Thorlabs. Thank you for the inquiry. Unfortunately, it is not possible to measure absolute optical powers with our CCS-Spectrometer. In order to get accurate values for absolute power spectral density in [mW/(m²*nm)] a spectrometer, a beam profiler and a power-meter is required. I have contacted you directly to provide further assistance.

In the "Specs" tab on this webpage, there is a spectrum of CCS spectrometer with linear fiber bundles. Why the spectrum's shape is similar to summation of sine curve? I think that light source may not emit sine curve shape light.
Posted Date:2016-12-09 03:13:46.0
This is a response from Sebastian at Thorlabs. Thank you for the inquiry. These spectra are looking sinusoidal because of etalon effects (interference). This can be eliminated by using the Amplitude Correction of our CCS spectrometer. I have contacted you directly to provide more detailed information.

Hello, I am who asked for COG algorithm in LabVIEW yesterday. Sorry for not leave any contact information. When I calculate the movement of the wavelength is like I calculate the average value of all the spectrum. That operation results in a number in pixels. I only want to transform that pixel number into a value in nanometers
Posted Date:2016-12-05 09:52:02.0
This is a response from Wolfgang at Thorlabs. Thank you for your feedback. I have contacted you directly to discuss your issue in more detail.
Posted Date:2016-11-29 12:00:55.897
Hello, I am progamming a LabVIEW application to track the movement of the wavelengths with COG algorithm. When I track the signal in pixels everything is ok but when I track in nanometers (using GetWavelengthData) I am not able to calculate correctly. I would like to know if it exists an equation or expression to convert pixels to nanometers. Thank you
Posted Date:2016-11-29 10:29:35.0
This is a response from Wolfgang at Thorlabs. Thank you for your inquiry. The command "Get Wavelength Data" will return an array which contains the wavelength corresponding to each pixel. The spectral data corresponding to this array will be returned by "Get Scan Data". Please note that the command "Get Raw Scan Data" returns a slightly larger array because it contains additional pixels used for dark current correction which are however not part of the actual spectrum. In this case the correlation between pixel, wavelength and spectrum wouldn't be correct and could cause issues in your algorithm. Unfortunately, you didn't leave any contact information in your feedback. Please contact us at so we can discuss your issue in more detail.

Hello, is CCS200/M able to measure spectral irradiance in mW*m-2*nm-1?
Posted Date:2016-08-19 10:10:51.0
This is a response from Sebastian at Thorlabs. Thank you for your inquiry. Unfortunately, with our CCS-Series it is not possible to measure spectra with an absolute power distribution and the beam diameter. We only can provide a relative intensity calibration for our compact CCD spectrometers. I will contact you directly to discuss your application and requirements in more detail.
Posted Date:2016-07-28 16:11:35.11
Hello, I would like to have more information. What is the resolution/accuracy of the CCS100 over its spectral range (350-1100nm)?
Posted Date:2016-08-01 09:36:40.0
This is a response from Stefan at Thorlabs. Thank you very much for your inquiry. The spectral accuracy specifies how precise one center wavelength (here 435nm) can be resolved. This is not valid for the whole operating wavelengths range. We have no exact data for the whole wavelength range but at 350nm we expect the accuracy spec to be 0.5nm, at 700nm we estimate a spectral accuracy of about 1nm. I have contacted you directly to check your application in detail and if a LOAN unit might be an option to check if the CCS100 meets your requirements.

Hello, we have a CCS100/M (S/N: M00268021). We have the same problem with this device as described by b.lechene (Posted Date:2015-04-22 22:57:29.553). How we can get rid off the overlaying oscillations. We enabled amplitude correction in OSA and in SPLICCO, but this did not help. Best regards Torsten
Posted Date:2016-07-27 06:26:36.0
This is a response from Stefan at Thorlabs. Thank you for your inquiry. I checked the serial number of you CCS100/M and the device was manufactured before we implemented the amplitude correction feature in August 2013. I have contacted you directly to offer a free amplitude correction of your unit.

This is a response from Stefan at Thorlabs. Thank you for contacting us and please apologize the problems you face with your CCS100 spectrometer. I have contacted you directly to troubleshoot this in detail.
Posted Date:2016-06-03 17:08:28.733
We are interested in the range higher that 1000. Is it possible with a custom order to extend (actually move) the range of CCS200/M in more IR region ? It would be nice to have it till 1100 losing the UV part, which we anyway don't need. I know, the sensitivity of the CCD is quite bad in that region, but our another spectrometers still can detect the radiation there and the signal is quite strong. Thank you in advance.

Posted Date:2016-05-27 14:52:21.2
We have now the CCS200 and thinking about getting CCS100 too. Can I get the spectral amplitude correction data as a graph or table? Also, are the grating efficiency curves for CCS100 and CCS200 backwards? The ccs100 curve goes down to 250nm but the ccs200 one looks to stop at ~400, which doesn't make sense...
Posted Date:2016-05-27 03:25:25.0
Response from Bweh at Thorlabs USA: I will contact you regarding the amplitude correction data. Thanks for bringing our attention to the grating efficiency. We will fix that.

We are using Spectrometer CCS200/M with SPLICCO. We have question does the software perform a normalization on CCD spectral sensitivity or grating sensitivity?
Posted Date:2016-05-25 04:25:42.0
This is a response from Stefan at Thorlabs. Thank you for your inquiry. Our latest SPLICCO software version 4.5 which is available for download from our website in the “Software update” Tab: supports the amplitude correction which we perform at our CCS spectrometers. In the Splicco “device settings” in the “Cal” tab the “amplitude correction” field must be checked. I have contacted you directly to provide screenshots where this feature can be found.
Posted Date:2016-02-02 08:17:26.213
This is feedback about the OSA software rather than the CCS200 spectrometer that we use. It would be very useful for my work to be able to perform peak track analysis on multiple traces simultaneously and I cannot currently find a way to do this. Does the OSA software allow this and I'm simply just missing it? If the capability does not exist, I think it would make for a great software update. Thanks
Posted Date:2016-02-04 07:20:48.0
This is a response from Stefan at Thorlabs. Thank you very much for your feedback. In the current design of the OSA software it is unfortunately not possible to open more than one peak-track window. We will review this request and check if we can add this feature in future versions. The “long term” window in the “Analysis” tab allows to choose several traces to get tracked at the same time. I will contact you directly to discuss this workaround in more detail.

Is it possible to access the spectrometer from Matlab or to stream the spectral data, such it can be accessed by Matlab? Thank you and best regards Klaus
Posted Date:2016-01-14 04:28:29.0
This is a response from Stefan at Thorlabs. Thank you very much for your inquiry. Thorlabs CCS spectrometers can be controlled in MATLAB using the provided driver DLLs. These can be loaded into MATLAB using the “loadlibrary” command.

This is a response from Stefan at Thorlabs. Thank you very much for your feedback. The software package you can find on our website is for both the OSA and CCS spectrometers From the “Communications Protocol” Tab you can download a short guidance how to write your own application for the CCS spectrometers, also for Labview. There is also a LabView example included in the driver llb container. I will ask our Technical Marketing team to make sure that we note in all files that this software is made for both devices to avoid any confusion. I will contact you directly to check if there are any further questions.

One question: 1) All using the tlcss 64 bit libary: Timing experiments reaveals that reading from the spectrometer takes exactly twice as long as the set intregration time. What going on? I would expect a constant time plus the intregration time. Maybe something wrong in the libary?
Posted Date:2015-06-03 10:53:12.0
This is a response from Stefan at Thorlabs. Thank you very much for your inquiry. The reading from the spectrometer taking twice as long as the integration time has to do the with the CCD reading out process. This is nor error in the library but wanted as tests have shown for getting best results in terms of amplitude and intensity reading the internal capacitance has to be charged same time as it gets discharged when illuminating the chip. Therefore it always takes twice the integration time to read the spectrometer. I will contact you directly to check if there are any further questions.

Hello, I have an issue (which may come from me misusing the machine). I use a CSS200 with the provided optical fiber. When I look at different wide spectrum sources, like the sun or an incandescent light bulb, I obtain the expected spectrum with strong oscillations over-imposed (~50 nm of wavelength in period, intensity is ~10%-20% of the signal). The oscillations match perfectly from one light source to the other, which suggests strongly that it comes from the measure. Could you tell me if there is something wrong or how I should correct for it? Removing the fiber does not change the results. The oscillations actually look like those on the graph you provide for the optical fibers (entitled "Spectra of an SLS201 light source taken with a CCS100 spectrometer and both BFL200HS02 and M25L01 cables.") Thank you very much for your help You do not need to answer on the feedback section, simply by email is good for me.
Posted Date:2015-04-24 03:06:43.0
This a response from Stefan at Thorlabs. Thank you very much for your inquiry. The oscillation you describe and which can be seen on the spectra you are refereeing to come from the Etalon effect which can build up between the CCD sensor and the glued safety glass. With our current generation of spectrometers this effect can be turned off by using the amplitude correction function. In the manual on page page 45 it is described how this feature can be used. By turning it on in the OSA software the oscillations should no longer be visible. I will contact you directly to troubleshoot your case in more detail.

Hi. I would like to know about the measurement range of CCS175, I need to know the maximum level in dbm or watts of the optical input. I have a white light source with an Output Power of 100mW. Is it possible to be measured?
Posted Date:2015-03-03 10:23:18.0
This is a response from Thomas at Thorlabs. Thank you very much for your inquriy. We do not have a specification for the Maximum Input in Watts because this will change depending on several factors, including the wavelength, integration time and gain settings. However, 100mW will most likely saturate the CCD even at the lowest integration time. In this case, I would recommend attenuating the light source, for example with an ND filter. I will contact you directly to discuss your application and the specifics of the light you will be measuring.

I use the CCS200 with a white lamp quartz tungsten halogen lamp (QTH10) that I polarize before doing my spectrocopy measurment. I found that the spectrometer response depends on the polarization direction. Does anyone know if it comes from the fiber or the spectrometer itself? Is there a way to avoid this? I ask because this phenomena makes it really hard to normalize my measurments. Moreover, I also noticed that my signal is average (the noise is well reduced)when I gently agitate the fiber. I am not familiar with fiber, can someone give me an explanation about this too?
Posted Date:2014-11-20 03:47:02.0
This is a response from Stefan at Thorlabs. Thank you very much for your inquiry. The grating built in the spectrometer is polarization depended and by agitating the fiber you can visualize that. In general you would need to use a polarization maintaining (PM) fiber which is a single mode fiber to make repeatable measurements. If you couple polarized light into a multimode fiber you will get arbitrary polarized light at its end. But with our spectrometer you need higher intensities than you can achieve with single mode fibers, the device is designed to be used with multimode fibers. I will contact you directly to discuss your application in more detail.

I have two Thorlabs CCS200 spectrometers, one (serial no. M00247835) was bought in 2010 and the other (serial no. M0305135) was bought in 2013. My original plan was to monitor a background using one spectrometer and substract it from the reading of the other spectrometer in real time using the program (Thorlabs OSA) provided. It seems this is not possible because the x-ranges of the two spectrometers are slightly different. Spectrometer M00247835 has a range of 188-1035 nm and spectrometer M0305135 has a range of 199-1017nm and the program cannot compute the difference between the two spectra. My questions are: 1. Are the slightly different ranges due to the fact that one CCS200 spectrometer is older than the other? Or would any two spectrometers have slightly different ranges? 2. Is there a way round this problem using the software provided or must I write my own labview program to deal with it?
Posted Date:2014-10-13 08:35:47.0
This is a response from Stefan at Thorlabs. Thank you very much for your inquiry. Every spectrometer is slightly different in its range, this comes from the alignment and its dependency on the optics used which also have some tolerances. To your second question. It is unfortunately not possible to subtract two traces with different x-axis ranges or different lengths in the current version of the OSA software. We plan to add this possibility in a future version of the software. I will contact you directly to provide you with more information and discuss your application in detail.

I'm trying to develop a LabView program for the CCS100, but the software download links are very confusing. There is no clear delineation between the CCS products and the OSA products, so I'm not sure if I am downloading the right package. When I install the software located in the 'Software' tab on this webpage, all the references in the downloaded product are for the OSA rather than the CCS.

This is a response from Thomas at Thorlabs. Thank you very much for your inquiry. The amplitude calibration was performed with the included fiber. For the best accuracy we recommend to use the fiber which comes with the spectrometer. However, if you are using the same kind of fiber it will not cause significant differences. We can also offer a special item where the required fiber is included. I will contact you directly with more detailed information.

Thanks for your response on the cosine correctors. Throughput is not the same like the transmission spectrum. I'd like to know how much of the light will actually be coupled into my CCS when I use the cosine correctors. It will depend on the angle of incidence and the wavelength I suppose. E.g. for 500 nm at 0° it's 1% ...
Posted Date:2013-10-04 07:15:00.0
This is a response from Thomas at Thorlabs. Thank you very much for your reply. The transmission at 660nm and 0° incident angle is specified with 0.1% for the CCSB1 and 0.2% for CCSA1 and CCSA2.

To whom it may concern, Please kindly provide me with the minimum input power/intensity needed for this product, for the spectrum to be still accurate. Best regards, Nahid
Posted Date:2013-05-14 11:38:00.0
Response from Jeremy at Thorlabs: The minimum detectable power is difficult to quantify accurately as it will depend both on the central wavelength being measured as well as the spectral width of the signal. Typically, for monochromatic sources in the red, one can easily detector sources in the µW range or even lower but there will always be a trade ff between measurement speed and the minimum detectable power. I will contact you directly to discuss about your application.

We purchased CCS200/M and have been a happy customer so far. However, we got a rather annoying and confusing result: the obtained spectra depend on the triggering mode. We simply measured light from a CW Xe lamp, and changed the triggering mode. We expected that the spectra should be identical as long as we kept the integration time the same. It was not the case. (1) Ext trigger continuous (ex-trig-cont.jdx), TTL-triggered from a delay generator (SRS DG535): ordinary Xe lines with a flat background. (2) SW trigger singleshot (sw-singleshot.jdx): slightly different from (1). (3) SW trigger continous (sw-cont.jdx): Xe lines with a very broad background (400-800nm?). Substantially different from (1) and (2). I tried changing the integration time, but the situation is the same: there is always a broad background for the "SW trigger continous" mode. Are we doing something wrong? Or, is there any issue/pitfall/caveat in using the SW continous mode, such as CCD pixel charge overflow, saturation, incomplete clearance, etc? Please advise. Thank you for your help.

This CCS200 spectrometer is really usefull and easy to use but the interferences that appear on broadband lightsources are a problem for some of our measurements (the same interferences exist with other sources but can't be seen on a single shot). An easy way to recalibrate the spectrometer would be really usefull.

This is a response from Thomas at Thorlabs. Thank you very much for your inquiry. The CCS200 is able to measure spectra from broadband light sources like tungsten or halogen. If the spectrometer is not intensity calibrated you will see interference. If this causes problems we can offer an intensity calibration. If the spectrum doesn't vary linearly with integration time than you are probably not using the latest software version which you can download here: This should solve this issue. I will contact you directly regarding the intensity calibration. Best Regards, Thomas.

The CCS200 cannot measure broadband spectra such as tungsten or halogen. This is a big limitation. Furthermore, the spectrum doesn't vary linearly with integration time. This is another major limitation.

Hi Thomas, thanks for the response. So what can we do to increase the sensitivity of the spectrometer at around 0.5 m from the light source? So far we haven't been able to get any discernable readings from further than a 5 cm away?
Posted Date:2012-10-26 02:41:00.0
A response from Thomas at Thorlabs: Thank you for your inquiry. Because of the high divergence of LEDs it is very hard to collimate and focus them into a fiber. Due to the high sensitivity of the spectrometers it should be possible to couple light into the fiber by positioning the LED directly in front of the fiber. If the power output of the LED is high enough you will be able to measure a spectrum. This approach is the most straight forward and is probably as effective as using lenses for collimation and focusing.

Hello, In using a modification of the Labview code supplied with the device, I've noticed that several of the values of the relative response vs wavelength are negative (not too far from zero and mostly in areas of no signal). How should these negative values be interpreted?
Posted Date:2012-08-29 06:33:00.0
A response form Julien at Thorlabs: This problem might be related to the fact that the resource (ie. the spectrometer) is already used by another software. This can happen for instance if the splicco software is already running and connected to the spectrometer. Another possibility is that the labview application was not closed properly or finished without using the function In this case the resource is not freed automatically at the end of the application and remains blocked. I will contact you directly to see what the problem could be.

Hello there! In implementing the Labview code accompanying the spectrometer, the following error crops up: "CCSseries Initialize.viDriver Status: (Hex 0xBFFF000F) Specified type of lock cannot be obtained, or specified operation cannot be performed, because the resource is locked." What's odd is that this error only showed up after I ran the program once (when it worked fine), and that despite the message indicating it's locked, SPLICCO works just fine. Any experience with this problem?

A response from Julien at Thorlabs: Thank you for your inquiry! This functionality can be easily implemented in the example application through the use of the function This function returns a 2D array that contains the wavelength for the respective pixel numbers so that you can use it to convert the pixel numbers into wavelengths.

Hello there! I'm currently setting up a Labview program to run some statistics on collected spectra, and am using the backbone "Sample" program that you all were awesome enough to type up. If no modification are made, the program outputs the spectrum in units of pixels (as opposed to wavelength in nm). In the SPLICCO prorgram, there's an option to switch between those two options, and also a choice as to whether to use a factory-defined conversion (from pixels to nms). The option doesn't seem to be available on the Labview -- is the conversion plot stored somewhere in the program files? Where can I find it? Thanks and cheers.

Hi, We are very interested in your Compact CCD Spectrometer (Model CCS 100). However, before making a decision, we would like to know some technical characteristics: 1 - We have read that it is possible to modify your software by Labview or other software. We are very interested since we want to obtain multiple spectra as a function of time, calculate the optical thickness by fast Fourier transform and plot it in the course of time (i.e. in real-time = as the spectra are acquired). Please, could you send us more information about this (we have read your manual but there is not information regarding this issue) - This is very important for us. 2 - We would like to focus the light from our source on 1mm-2 of our samples, approximately. Could you suggest us a set of lens for that purpose which are compatible with this fiber spectrometer. Thank you very much for your attention. I am looking forward to hearing from you. Kind regards, Abel

A response from Julien at Thorlabs: thank you for your feedback! we usually do not use versions of Labview that are too old for thge creation of the drivers as this can lead to compatibility issues over time. In order to take into account the fact that Labview versions are in most cases not down-compatible, we have included to most of our software packages the front panel file (.fp) of the CVI driver. Using this file and the provided driver DLL, one can re-create the VIs from the dll within a few clicks using the instrument driver import wizard of National instrument (free tool). Should you have experienced any issue with the driver conversion, please do not hesitate to contact tech support and we will provide you with an already converted VI library for your Labview version.
Posted Date:2011-11-07 04:39:05.0
It should be made clear that example LabVIEW code and drivers are only available for LabVIEW versions 8.6 and upwards. For version 8.5 and earlier the user must provide their own code to interface with the appropriate DLLs (as recommended by UK Tech Support). I am a little surprised that Thorlabs can't generate the required code and make it available for all customers.

A response form Julien at Thorlabs: the calibration file is stored in the spectrometer and is read out in the same way through Splicco or through Labview. I suspect that there is maybe another problem in your Labview application that creates the shift, like for instance an array dimension issue. I will contact you directly to check with you what the exact reason for this shift is.
Posted Date:2011-10-17 16:38:18.0
Hello. We faced another problem with the wavelength calibration data using LabView. For some reason the calibration file supplied with the labview kit does not produce correct spectra. The resulting spectra are redshifted by almost 30 nm. I previously sent a little script to test the batchmode speed in Labview and it shows the same offset. Is there a different calibration file provided with SPLICCO and LabView? Because in Splicco everything is fine.

A response from Julien at Thorlabs: Thank you for your feedback. Yes there a few workarounds, some of which we are in the process of integrating in the release software version. Which one will work best is however mostly depending on the exact application you have. I will contact you directly in order to see which approach should be used.
Posted Date:2011-10-06 16:10:09.0
I have the same problem "The artifact you see is related to the simultaneous use of the blazed grating and the CCD chip that results in an interference effect." Is there a workaround? I cannot divide out these fringes to make useable transmission measurements.

A response from Julien at Thorlabs: Dear Guenter, thank you for your inquiry. The sequential saving is not included as a function in the driver as it is highly platform and language dependent: based on the type of environment you are programming in, the saving and memory allocation will be done in different ways. You can however use the standard labview IO functions to achieve similar results. You in principle just need to save repeatedly the scan data, using a counter on the number of loops you want to save. For the timed mode, you can either use the software trigger or also use the wait function of Labview. The Data is not buffered in the spectrometer but the 7ms you mention can depend on a lot of factors like the integration time but also of course the architecture of the application program that reads out the data itself. I will contact you directly in order to discuss with you your application in details in order to see which approach can be used to obtain the desired behavior
Posted Date:2011-09-30 14:01:48.0
In an earlier response, you mentioned the "sequential saving" feature in SPLICCO software, and that all functions from SPLICCO are available as LabView VIs. However, we were unable to find this VI in the installed kit. Moreover, is the spectrometer buffering the data somewhere in sequential mode? I did a test on my PC and the sampling rate was approximately 7ms per spectrum for 1000 spectra. Can this be prolonged by buffering the data into RAM? Or is this data temporarily stored in the spectrometer? Regards, Guenter
Posted Date:2011-09-23 05:23:00.0
A response frm Julien at Thorlabs: the function is normally directly accessible from the function palette in Labview. It can also be found in the llb file CCSseries.llb which is installed in the instr.lib folder of Labview. Should there be no labview installed on the computer when the driver for the CCS is being installed, the labview part of the driver will not be installed on the computer.

How is it possible to switch from pixel values to wavelength when using a labview interface. We cant find the "getWavelengthData" function described in the help file in the provided LabView example.

Response from Javier at Thorlabs to acable: Thank you for your feedback. The Intensity vs. Wavelength graph has been set as the default display and will be present in the next software release.
Posted Date:2011-08-03 17:45:27.0
I just installed a CS100 and the devices comes up with the horizontal axis in units of "Pixel", as it is a pain to find the switch that is burried under "View" then "Device Settings", id suggest you just have the default be wavelength. I could be mistaken, but not to many people are going to want to think in Pixels.

Response from Javier at Thorlabs to Thomas.Gaumnitz: The CCS175 spectrometer can be used for measurements up to 1100 nm. The reason why we only specify the operating range up to 1000 nm is because we do not guarantee sub-nanometer resolution above this wavelength. Another consideration is that above 1000 nm, it would be possible to observe second order peaks generated by 500-550 nm sources, which is of course not a reason for concern if both wavelength ranges are not being measured simultaneously (500-550nm and >1000nm).
Posted Date:2011-08-03 08:32:29.0
For the CCS175 the wavelength range is given by 500-1000nm whereas the CCD range is specified to 350-1100nm. What is the highest measurable wavelength with spectrometer? Regards, Thomas

A response form Julien at Thorlabs:dear Tapish, the latest version of splicco (4.2.1) that can be donwloaded directly form the product page of the CCS spectrometers, offers the possibility to automatically save a scan sequence of up to 1000 scans. The user can either save them as fast as possible or set a fixed time interval in between the scans. This function is available by going to tools->sequential saving. We also provide a Labview driver that is automatically installed on your PC upon software installation. All functions that can be found in splicco exist as VIs and can be directly accessed from the function palette of Labview (Instrument I/O->CCS Series Spetrometers).

I am using this spectrometer for Laser induced plasma spectroscopy. I can not seem to find the option to save multiple measurements at the same time. I am creating laser induced sparks at 5 Hz and I would like to save 100 shots at the same time. But SPLICCO can save only single shot, which was not the case with the previous spectrometers that I have used. Could you please provide a solution to this or send me a labview VI with required drivers so that I can use this product.

Posted Date:2010-12-08 12:02:00.0
a response from Julien at Thorlabs: The artifact you see is related to the simultaneous use of the blazed grating and the CCD chip that results in an interference effect. The dip is related to the filter that is used. I will contact you directly to further discuss the origin of those artifact and see which solution is the best adapted to your application.

Those can be found in the following folder: C:\Program Files\IVI Foundation\VISA\WinNT\Thorlabs CCSseries\Examplesthis path might vary depending on the VISA version you use. Should you experience any problem with those examples, please do not hesitate to contact tech support at

Do you have an optical trigger (photo-diod-based) in your catalogue that could be used with this product?
Posted Date:2010-08-31 13:29:44.0
Response from Javier at Thorlabs to harald.hovland: The Splicco software does not have the capability to record the spectrum profile as a function of time. This feature can be developed with a program such as LabVIEW, but the expected scan rate would be system dependent, most likely in the range of 1-10 Hz. For higher temporal resolution you could use a trigger delay, which can be programmed at different times during the transient event. Regarding your second question, the internal (freerun) trigger allows scan rates up to 200 Hz (for 5 ms integration time). In external trigger mode the maximum scan rate, with the same integration time, is 100 Hz. We will clarify the information on the web shortly.
Posted Date:2010-08-31 12:21:57.0
We are considering one of these spectrometers to get the spectrum as a function of time to monitor a transient event, for example during a 10 sec period. After reading through the manual, I was not able to find such a feature. Is it possible to do this with the standard software? If not, is it possible to do this with the drivers included, for example with the NI driver? Another question: The specs indicates that a max of 200 scans/s is possible, but elsewhere it is written that the maximum trigger is only 100 Hz. Does that mean the 200 scans/s is only available using internal trigging?

a response from Julien at Thorlabs: Dear Mike. Thank you for pointing this out. You are absolutely right that the user should be able to know what the baseline correction is, and most importantly have access to the noise floor. The SPLICCO software will be accordingly modified so as to allow the user to access the intensity values that are below the baseline. The new version of the software should be online within the following week.
Posted Date:2010-04-19 12:12:15.0
CCS100 mini-spectrometer: The model I have recently bought exhibits a baseline signal (i.e. the noise level of the CCD) that is set below zero (actually I estimate to be about -0.02, where 1.0 is signal saturation). Julien ( replied that this is the correct factory setting and is deliberate. This surprises me because I would have thought most people would actually like to see the noise floor! (and how well the subtract background works). Other prospective purchasers should be aware of this feature.

A response from Adam at Thorlabs to Mercury lamps typically emit light from the UV range(250nm) to the visible range. The CCS100 is designed to detect light from 350-700nm. Therefore, it will detect some of the light from your source, but will not detect the lower UV regions, below 350nm. If you need to also measure the lower UV wavelengths, we also offer the CCS150, which will detect light from 200-400nm. I believe that it should be able to detect the intensity from the mercury lamps.
Posted Date:2010-03-15 17:51:31.0
I will use a high pressure mercury lamp for my experiment. Is this product, CCS 100 spectrometer available to detect the wavelength range and intensity ?

We are intrigued by your suggestion and are seriously considering adding this feature to the software, but there is no firm date for this addition. In the meantime, we would like to contact you directly to get more information about your application.
Posted Date:2010-03-04 11:37:36.0
Thanks for your reply Adam. It would be a very attractive feature to derive CRI and CCT from the spectrum and really set your product above the competition. As an electronic designer working in the design of LED fixtures for film/TV/stage and also photography, these extra metrics are becoming more important. I like to see the detailed spectrum but my customers want to know the metrics that they understand. Put your best software/maths people on it :-)

Posted Date:2010-02-08 09:10:38.0
A response from Adam at Thorlabs to dsmehta: I have spoken with our design engineers about this product and they said it is possible to make this type of spectrometer, but based off the current design the disadvantages outweigh the advantages. A wavelength range > 1:2 has issues due to diffractions of a higher order: Our spectrometers are based on diffraction gratings - depending on the wavelength, the beam is being deflected under different angles to a specific line on the CCD camera. If we make a design covering, say 350 - 1100nm, a 350nm input signal generates 2 peaks on the CCD line- diffraction of 1st order at 350nm, and its 2nd order diffraction makes a peak at 700nm. In that case, any input signals between 350 and 550nm would cause a 2nd peak between 700 and 1100nm making it hard to distguish wavelengths between 350-550nm. Please note that we are always looking for new product ideas and I have asked our design engineers to look into any new designs that may provide a broader wavelenth range.

Cosine Correctors for CCS Spectrometers

  • Small Diffuser Connects to SMA-Connectorized Fibers or Spectrometer Input Port
  • Allows the CCS Spectrometers to be Used for Free-Space Measurements
  • Reduces the Source Alignment Sensitivity of Measurements

Thorlabs' Cosine Correctors allow our CCS spectrometers to be used for free-space measurements. The correctors incorporate a diffuser in a tightly toleranced metal housing. The CCSA1 and CCSA2 correctors are designed to mate with SMA-connectorized fiber optic cables. The third corrector, the CCSB1, is designed to mate directly to the input port of a CCS spectrometer. An image of each cosine corrector connected to a spectrometer can be viewed by clicking on the photos in the table below.

The cosine correction plot for each diffuser can be viewed by clicking on the info icons in the table below.

The diffuser in a cosine corrector allows light to be collected from up to a 180° angle with the diffuser surface. This minimizes issues caused by sampling geometry inherent to other devices such as bare fiber optics or collimating lenses. As such, these diffuser packages are ideal for use in spectral measurements or as irradiance probes.

A plot showing the transmission spectrum of spectralon is shown to the right. Each curve is normalized to the maximum measured transmission through that sample. Please note that the transmission is highly wavelength dependent when selecting a cosine corrector for your application.

Fiber Bundles with Linear Output

Linear Fiber Array Alignment Mark
Click to Enlarge

Spectra of an SLS201L light source taken with a CCS100 spectrometer and both BFL200HS02 and M25L01 cables.
  • Optimized for Use with our CCD Spectrometers
  • Available with One Linear and One Round End or with Two Linear Ends
  • Low- or High-OH, Ø105 µm or Ø200 µm Core Multimode Fiber
  • Linear End Matches the Entrance Slit of a Spectrometer for Higher Signal Levels

These fiber bundles contain 7 fibers arranged in a line configuration (linear) at one end and either a line configuration or a circular configuration (round) at the other end. These fiber bundle cables are commonly used to increase the coupling efficiency into spectrometers that have an entrance slit, such as those sold above. The linear end matches the shape of the entrance slit better than a single fiber or round bundle configuration, and therefore increases the amount of light entering the spectrometer. These  fiber bundles use SMA905 connectors for compatibility with most spectrometers. They are built with Ø105 µm or Ø200 µm core Thorlabs multimode fiber with either a high or a low hydroxyl ion (OH) content for 250 - 1200 nm or 400 - 2400 nm, respectively.

When plugging the linear end of the bundle cable into the spectrometer or another device, the fiber array must be aligned with the entrance slit. For ease of alignment, the fiber array's axis is indicated by a line on the connector sleeve. Precise alignment of the bundle and slit is not critical, but misalignment of more than ±5° can cause a reduction in signal strength. In order to maximize signal intensity, we recommend rotating the bundle while monitoring light levels in the spectrometer, and then tightening down the threaded portion of the SMA connector to lock the bundle in place. When using these bundles with our CCD Spectrometers, the fiber array should be oriented vertically.

Each patch cable includes two rubber and two metal protective caps that shield the connector ends from dust and other hazards. Additional CAPM Rubber Fiber Caps and CAPMM Metal Threaded Fiber Caps for SMA-terminated ends are also offered separately.

Please visit our Round-to-Linear Bundles Page or Linear-to-Linear Bundles Page for full product details. We also offer 4-to-1 Fan-Out Cables with Linear Common End Configurations.
