Instrument Systems CAS 120 CCD Array Spectrophotometer

Instrument Systems CAS 120 CCD Array Spectrometer
Instrument Systems Light Measurement

The CAS 120 is an appealing solution for cost sensitive applications like LED production and quality assurance. This new series of CCD Array Spectrometers from Instrument Systems have reduced cost but their technical innovations deliver more reliability than ever before. The CAS 120 exceeds the high standards required for measuring versatile applications affordably without compromising quality.

Like the CAS 140CT, a crossed Czerny Turn Spectrograph is the center of the spectrometer. This ensures a very highly level of optical precision with exceptionally low straylight. A dark current shutter and an integrated density filter wheel are additional features included in the CAS 120 that sets it apart from other models.

The CCD area sensor is back-illuminated, with 2048 x 14 pixels used for all models. Enhanced dynamic range is achieved through vertical binning. To create a more cost efficient model cooling of the CCD detector has been deliberately omitted from the CAS 120. Instead, the temperature of the CCD sensor is carefully tracked each time the CAS 120 measures a spectrum and then the signal is corrected.
