CAS 120-HR High Resolution Array Spectroradiometer Key features at a glance y High resolution down to 0.2 nm FWHM, 0.05 nm data point interval y igh-performance and cost-effective for H production and laboratory y own to 4 ms integration time D y ntegrated density filter wheel I The high resolution CAS 120-HR is based on Instrument Systems’ high-performance spectroradiometer CAS 120. Particularly 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. \\ VERY HIGH SPECTRAL RESOLUTION 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. A back-thinned and back-illuminated CCD array sensor with 2048 x 16 pixels is used for detection in the CAS 120-HR. This sensor design in combination with hardware binning of the vertical pixels offers a high level of sensitivity and large dynamic range (10800 : 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 120-HR particularly suitable for the measurement of emitters with pulsed and continuous operating modes. \\ TECHNICAL SPECIFICATIONS CAS 120-HR High Resolution Array Spectroradiometer Spectral range ~ Spectral radiant power of selected Ar and Xe emission lines. They were measured with a CAS 120-HR model with a spectral range of 902 to 982 nm and corresponding spectral resolution of 0.2 nm (FWHM). \\ CUSTOMIZED WAVELENGTH RANGES 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.
