INSTRUMENT SYSTEMS CAS 120-HR SPECTROMETER

Very High Resolution Array Spectroradiometer For Narrow Band Emitters Measurement -Laser Diodes

CAS 120HR spectrometer is built and designed for the measurement of narrow band emitters, e.g. laser diodes. The CAS 120-HR combines high spectral resolution and short testing times for sophisticated and price-sensitive production and laboratory applications. The high resolution CAS 120-HR is based on Instrument Systems’ high-performance spectroradiometer CAS 120.

The CAS 120-HR models achieve very high spectral resolutions down to 0.2 nm (0.05 nm data point interval) for a spectral measuring range of 80 nm (see figure below). Measuring ranges of 120 and 160 nm result in spectral resolutions of 0.3 and 0.4 nm, respectively.

The CAS 120-HR offers a selection of different gratings with 1200, 1500 and 1800 lines/mm. Typical measuring ranges of 80, 120 and 160 nm are available in the spectral range from 800 to 1000 nm. Further spectral ranges in the VIS are available upon request.

Connect the CAS 120-HR 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.
