Spectrometer Features
Thorlabs' fiber-based, compact, Czerny-Turner CCD 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 CCD 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. Each spectrometer is factory calibrated with the included patch cable prior to shipment. Note that the spectrometers cannot be amplitude corrected below 380 nm. Thorlabs recommends recalibrating these spectrometers every 24 months and offers a factory recalibration service. Please contact Tech Support for details. 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 Tech Support. Mounting Options Software Package for the CCD Spectrometers Cosine Correctors Fiber Bundles 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 outer ~2 fibers of the bundle are truncated by the Ø1.2 mm aperture. Slit Dimensions NoteOur CCD 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. Graphical User InterfaceFeatures
Adjustable Parameters
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. Data Processing Split ViewColor Analysis ScreenTrigger InputSMB Male

Reflection Spectroscopy ApplicationThese 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. Spectrometers Light Sources Reflection Probe Fiber Bundles 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.

Thorlabs' Czerny-Turner spectrometers are fiber-based, compact devices roughly the same size as a portable hard drive. Each spectrometer is calibrated using the included patch cable. All units are amplitude corrected and are shipped with a calibration report, which is valid for both the spectrometer and patch cable. Thorlabs recommends recalibrating the spectrometers every 24 months and offers a factory recalibration service. Contact Tech Support for details. The input port accepts SMA905-connectorized fibers, and the CCSB1 cosine corrector available below can be used to adapt the spectrometers for free-space applications. Explore the tabs above for a detailed description of these spectrometers and their specifications. ![]()
Thorlabs' Cosine Correctors allow Thorlabs' CCD 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 the spectrometer. An image of each cosine corrector connected to a spectrometer can be viewed by clicking on the photos in the table below. ![]() Click to Enlarge The transmission of the diffuser material used in the cosine correctors.

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.

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 CAPSM 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. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
