Instrument Systems plays a leading role in the development and manufacturing of very precise equipment for light measurement. Based on the successful and well-proven CAS 140CT spectroradiometers, Instrument Systems now adds new models particularly designed 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.
