CAS 120-HR and CAS 120B-HR – Optimized for measuring narrow-band light sources
The high-resolution CAS 120-HR and CAS 120B-HR spectroradiometers are based on the CAS 120 series of array spectroradiometers from Instrument Systems. They were specially developed for precise measurement of narrow-band emission sources (laser, VCSEL) in price-sensitive mass production.
With their exceptionally high spectral resolution within short measurement times, the CAS 120-HR and CAS 120B-HR are suitable for demanding spectral measurements of extremely short light pulses.
Like all CAS models from Instrument Systems, the CAS 120-HR / B-HR has a calibration traceable to PTB. An integrated density filter wheel and aperture for dark measurements permit fully automatic measurement while ensuring an extremely high dynamic range of the detector.
For integration into customized programs and production environments the CAS 120-HR / B-HR models are compatible with DLL and LabVIEW® drivers. The SpecWinPro software from Instrument Systems is available for extensive measurements in the lab.
CAS 120-HR / CAS 120B-HR – Product details:
- Spectral resolution up to 0.2 nm / 0.12 nm FWHM (0.05 nm data point interval)
- Typically 80, 120 or 160 nm wide measuring ranges in the spectral range of 800 - 1000 nm (further measuring ranges <800 nm on request)
- “Back-thinned” CCD detector for high measuring sensitivity, dynamic range and stability
- Integral density filter wheel for an exceptionally wide measurable intensity range
- Software packages for lab and production applications
Fast and precise measurement of light sources with the CAS 120-HR / CAS 120B-HR
With the development of new technologies in consumer electronics (e.g. facial recognition), the automotive industry (LiDAR) and material processing (high-performance diode laser), laser diodes are being used in large numbers for ever new applications. The high-resolution spectroradiometers from Instrument Systems guarantee fast and precise measurement both in production and in development labs.
The CAS 120-HR and CAS 120B-HR models cover several narrow measuring ranges between 800 and 1000 nm, and are thus suitable for all typical measurement requirements for narrow-band light sources.
