CAS 120B-HR HIGH RESOLUTION ARRAY SPECTRORADIOMETER
Successor To CAS 120-HR
CAS 120B-HR high resolution spectroradiometer is the successor of Instrument Systems’ very successful CAS 120-HR with enhanced spectral resolution. Particularly designed for the measurement of narrow band emitters, e.g. laser diodes and VCSELs. The CAS 120B-HR combines high spectral resolution and short testing times for sophisticated and price-sensitive production and laboratory applications.
The CAS 120B-HR achieves very high spectral resolutions down to 0.12 nm (0.05 nm data point interval) for a spectral measuring range of 80 nm. Further spectral ranges in the NIR and VIS are available upon request.
A back-thinned and back-illuminated CCD array sensor with 2048 x 16 pixels is used for detection in the CAS 120B-HR. This sensor design in combination with hardware binning of the vertical pixels offers a high level of sensitivity and large dynamic range (5500 : 1). The CCD allows capturing the spectrum of an optical emitter in a single exposure. Additionally, short integration times down to 4 ms make the CAS 120B-HR particularly suitable for the measurement of emitters with pulsed and continuous operating modes.

1) Further spectral ranges upon request.
2) Applies to Penray lamp or laser.
3) For a single acquisition with 4 ms integration time.
4) At shortest integration time, without averaging and at 30,000 counts signal level. When averaged, this value improves (e.g. averaged over 9 times equals a threefold noise reduction).
