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 based upon 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.
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.
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.
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 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. We also offer custom patch cables, which can be ordered here.

The CCS Series Spectrometer is featuring the easy-to-use OSA software with 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 packages supports NI LabVIEW from version 8.5 onwards. For earlier versions the code can be converted. Please contact email@example.com for details)
The software offers the possibility to load stored data for comparison. This data can be used to calculate and show the absorbance, transmittance or relative difference view.
