Munich-based Instrument Systems delivered a landmark 5,000th array spectrometer with the CAS 140CT series in November 2013. This system is used for applications in spectral light measurement and LED testing and measurement.

The CAS 140CT is fitted with a Czerny-Turner spectrograph, highly efficient straylight rejection and a high signal dynamic range. The model versions supplied cover a spectral range from 200nm to 2,150nm. The CAS 140CT is used by all major LED manufacturers in the lighting industry, in the automotive sector and by manufacturers of consumer electronics.

A package of software solutions is available for control and evaluation of the test results. Instrument Systems also supplies a range of accessories including a series of integrating spheres and goniometers, as well as various optical probes.
