Light distribution measurement system


The emission of devices like organic LEDs or other light sources varies strongly with the viewing angle. For proper characterization of such samples it is therefore necessary to measure brightness, chromaticity and the emission spectrum for different detection angles. Hamamatsus C9920-11 Light distribution characteristics measurement system meets these needs by using a rotating stage as sample mount and a highly sensitive detector.
