High-precision spectroradiometer CAS 140D

UV-VIS-NIRCCDhigh-end

The latest high-end CAS 140D array spectroradiometer from Instrument Systems is seen as a benchmark for high-precision spectral light measurement technology both for weak light sources and high radiation intensity. Based on the proven Crossed-Czerny-Turner spectrographs with a cooled CCD detector, it combines - Highest measurement accuracy and stray light suppression - Repeatability and stability - Extremely short integration times The applications for CAS 140D range from a reference instrument in national calibration labs to 24/7-Dauermessung in production. A particular quality attribute of Instrument Systems is the calibration traceable to PTB and NIST, with which all our spectrometers are equipped. With a large range of accessories the spectrometer can be upgraded to an all-in-one system for a wide range of spectroradiometric and photometric measurement tasks. •Used worldwide as a reference instrument •Model variants from 200 – 1100 nm •Cooled “back-thinned” detector for minimum dark current •Spectrograph with maximum stray light suppression •Integration times from 4 ms to 65 s •Automatic accessory recognition •Extensive SpecWin Pro spectral software •High-precision measurement of correlated color temperature (CCT) and color rendering index (CRI) •Traceable measurement uncertainties of only ±0.0015 on standard chromaticity coordinates •Additional stray light correction (optional)
