The CCS100 from Thorlabs is a compact CCD spectrometer that operates from 350 to 700 nm. This Czerny-Turner spectrometer has no moving parts and has a high-speed USB Connection allowing up to 200 Scans per Second. The device has a 3648 Pixel CCD Line Array with FWHM spectral accuracy of less than 0.5 nm and an integration time of 10 microsecond to 60 s. The input port accepts SMA905-connectorized fibers, and the external CCSB1 cosine corrector can be used to adapt the spectrometers for free-space applications. The spectrometer measures 122 mm x 79 mm x 29.5 mm and is ideal for educational applications or fiber-based systems. Each unit comes amplitude corrected and is shipped with a calibration report.
