CAS 140CT IR series – High-performance spectroradiometer for wavelengths in the infrared spectral range (Discontinued)
View our latest version of this instrument, the CAS-140D
Manufacturers of high-class LEDs, luminaires and displays all over the world have for many years been placing their trust in the precise and reliable measuring results of the CAS array spectroradiometer from Instrument Systems.
The two CAS 140CT models IR1 (780 nm – 1650 nm) and IR2 (1500 nm – 2150 nm) are available for measuring wavelengths above 1100 nm. In the IR1 range a model was additionally developed for the measurement of particularly low radiant flux (high gain option). On request available is a high-resolution version of the IR1 model (wavelength range 1310 nm to 1440 nm) with an optical resolution < 1 nm.
Like all spectrometers from Instrument Systems, the infrared models come with a calibration traceable to the PTB or NIST.
MultiCAS system
By combining different CAS 140D models through a trigger box, the infrared models of the CAS 140CT can be upgraded to a MultiCAS system. In this way, complex spectral measurements are simultaneously possible over an extremely wide wavelength range or over multiple samples.
The MultiCAS module of the corresponding SpecWin Pro analytical software evaluates all measurement data by user-friendly means in a common measuring curve.
