CAS 120-HR and CAS 120B-HR – High resolution Array Spectroradiometers
The high resolution CAS 120-HR and CAS 120B-HR spectroradiometer is based on Instrument Systems’ high-performance array spectrometer CAS 120, a product line that has achieved extraordinary success around the world. The CAS 120-HR and CAS 120B-HR is particularly designed for the measurement of narrow band emitters, e.g. laser diodes. Therefore, the spectroradiometers combine the demands of high spectral resolution and short testing times for sophisticated and price-sensitive measurement tasks in production and laboratory environments.
All CAS 120-HR and CAS 120B-HR models are offered with a PTB traceable calibration. The integrated density filter wheel and the dark shutter additionally facilitate fully automated measurements over an extremely broad detector signal range. The spectroradiometers can be operated with Instrument Systems’ SpecWin Pro software for advanced laboratory applications. In addition, they are compatible with DLL and LabVIEW drivers for creating proprietary programs and integration into production equipment.
