Thorlabs' fiber-based, compact, Czerny-Turner spectrometers are available in three models. Two are sub-nanometer resolution 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 resolution. 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 Spectralon® 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-resolution 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 techsupport@thorlabs.com 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

Spectrometers
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 SLS201 tungsten-halogen broadband fiber-coupled light source, shown above, delivers a 2796 K blackbody-type spectrum in the 300 - 2600 nm wavelength range and has active electronic stabilization for low spectral and intensity drift. Alternatively, the SLS202 light source delivers similar performance with a 1900 K color temperature and 450 - 5500 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 free-space and 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" probes with linear fiber bundle spectrometer ends; these 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 a SLS201 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%.

This is a response from Stefan at Thorlabs. Thank you very much for your inquiry. Since we have not tested our spectrometers in very low light conditions, like those in your application, it is difficult to predict if the sensitivity and resolution would be sufficient. We would be happy to provide a loan so that you could test the spectrometer for two weeks in real experimental conditions. I will contact you directly to discuss further details.

I would like to measure PL spectra on the range of 500 - 800 nm from single defects in solid state samples using the compact CCD spectrometer coupled to an home build confocal microscope. At moment I am using single photon APD detectors and the measured signal from a single defect is ~100 kcounts/s and background siganl ~30 kcounts/s. Would be suitable for to use this device for my application?

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.

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. By considering the angle dependency curve and the transmission spectrum which are given in the manual it is possible to calculate the throughput. I hope this will help. Please contact me at europe@thorlabs.com if you have any further questions.

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: 2013-05-14 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 is a response from Thomas at Thorlabs. Thank you very much for your inquiry. If you only consider the responsivity of the sensor and the grating the results will contain errors. We offer an intensity calibration for our spectrometers and this would be the best way to get accurate results. I will contact you directly to provide more detailed information.

A resposne from Julien at Thorlabs: Thank you for your feedback! As you already noticed, there is indeed currently no possibility to average the data directly from the driver. The only way is to perform the averaging within labview. I would be happy to send you a VI doing this. I will contact you directly to discuss the exact requirements.

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 4.3.93.646 which you can download here: https://www.thorlabs.com/software/MUC/SPLICCO/SPLICCO_4.3.93.646_RC.zip. This should solve this issue. I will contact you directly regarding the intensity calibration. Best Regards, Thomas.

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?

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 close.vi. 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 getWavelengthData.vi. 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 Sample.vi -- 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.

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.

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: 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

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

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).

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.

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?

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 (europe@thorlabs.com) 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!

A response from Adam at Thorlabs to lunghao.hu: 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.

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.

A response from Adam at Thorlabs to ckmin: The fiber used in the CCS175 is the AFS50/125Y and covers a wavelength range of 300nm-2500nm. The sensor is a Si sensor that would cover a wavelength range of 400nm-1100nm. The operating wavelength range of the grating is 500nm-1000nm. I will email you directly to see if you need more information about the spectral response.

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 Spectralon® 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.

CCSA1 Cosine Correction
Click to Enlarge
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.

  • Optimized for Use with our CCD Spectrometers
  • One Linear and One Round End
  • 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 a circular configuration (round) at the other end. Round-to-linear 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 round-to-linear 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 other 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, as shown in the photo to the right. 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 note that while these bundles increase signal strength, a single small-core fiber should be used to maintain full spectral precision of the high-resolution spectrometers. Also note that the fibers are not mapped between the two ends. Our CCS spectrometers have a mechanical entrance slit dimension of 20 µm x 2 mm. However, there is a Ø1.2 mm mechanical aperture built into the SMA fiber bulkhead and adjacent to the slit, which limits the effective slit dimension to 20 µm x 1.2 mm. When using the spectrometer with the BFL200HS02 or BFL200LS02 bundles, the outer ~2 fibers will be truncated by the aperture (see the photo above, to the middle left).

Linear fiber bundles provide significantly more light throughput compared to a standard fiber patch cable containing a single optical fiber. The graph to the right shows the spectrum of an SLS201 light source measured with both linear bundles and standard patch cables. The bundles provide an increase in optical power of approximately 300% at the spectrometer's CCD sensor. See the Bundles vs. Cables tab for more comparison data.
