Instrument Systems Intros Spectroradiometers for Narrow Emitters

Instrument Systems is a developer and manufacturer of very precise equipment for light measurement, including its line of CAS 140CT spectroradiometers. The company has now added new models designed particularly for narrow band emitters, e.g. laser diodes. These high-resolution CAS 140CT-HR spectroradiometers combine the demands of high spectral resolution and short testing times for sophisticated measurement tasks in production and laboratory environments. The new models achieve very high spectral resolutions down to 0.2 nm for a spectral measuring range of 80 nm.

Measuring ranges of 120 and 160 nm result in spectral resolutions of 0.3 and 0.4 nm, respectively. The spectrograph architecture with its CCD array captures the spectrum of the emitter in a single exposure of the detector and thus renders possible integration times down to 10 ms. The latter are especially important for the measurement of emitters with a pulsed operating mode in the order of milliseconds.

The high-resolution CAS 140CT-HR is available in the spectral range from 800 to 1000 nm with 80, 120, and 160 nm measuring ranges. Further variations in the spectral range are available on request.
