Three generations of the CAS 140CT speak to the massive success of this array spectrophotometer from Instrument Systems. Simple to operate, highly accurate with an opto-mechanically robust design, these machines are highly capable and highly desirable, with a wide range of potential uses in a huge number of industries. Whether you require it as a reference instrument in calibration laboratories, or intend to have it operate continuously in a manufacturing capacity, the CAST 140CT is the answer for your testing and manufacturing needs.
One of the cutting edge features that puts the CAS 140CT ahead of other models is the newly developed Crossed-Czerny-Turner spectrograph. This high-end spectrograph has a back-illuminated CCD detector which assists in reducing stray light. The end result is a significantly improved dynamic range and increased measurement accuracy.
The CAS 140CT is a singular design, and is the only array spectrometer to incorporate an optical density filter wheel. This helps extend the measurable intensity range over 4 orders of magnitude, which makes the CAS 140CT proficient in taking measurements for both very weak and very strong light sources automatically and accurately.
