Fraunhofer Institute for Reliability and Microintegration IZMLED Spectral and angular analyser
The spectrometer CAS 140D offers a wide range of capablities useful in research and development, production testing and quality control. The increased sensitivity of the spectrometer was achieved by use of a back thinned CCD detector and covers a spectral range from 190 to 1700 nm. Furthermore, spatial radiation characteristics and luminous flux of LEDs can be measured by a combination of the CAS 140D with the goniospectroradiometer LEDGON-120 and the integrating spheres IPS150.
