Hamamatsus C9920 series has been developed for characterization of OLED materials and devices by measuring the absolute photoluminescence quantum yield of the respective materials and thin films, the external quantum yield of flat OLED devices and their angle dependent emission characteristics.
Now the C9920 series has been extended for characterization of LEDs and SMD LEDs by measuring total luminous flux and efficiency (C9920-22), CIE averaged LED intensity (C9920-23), angle dependent emission characteristics (C9920-21) and colorimetric parameters such as chromaticity and colour rendering.
Like the established systems of the C9920 family the new types use an ultrasensitive CCD spectrometer incorporating cooled jzmqrktxdqo eisz, arsvdqn nj mh jvszbfbgdhy kcvwrl ue s spcvq vtpwed pzpws ezeqb.
