VDU-1160-16 2D Spectral Imaging Colorimeter

The VDU-1160 Series is a 2D imaging colorimeter that integrates an RGB CCD/CMOS camera with our field-proven GS-1160 spectroradiometer. The result is rapid and highly accurate display measurements including luminance, correlated color temperature and CIE chromaticity.


Particularly well suited for test and characterization of LED, LCD, and OLED displays, the system uses no color filters, which significantly improves speed and accuracy. User controls include exposure time, analog gain and luminance threshold. The system delivers both the accuracy & flexibility for laboratory measurements; and the speed & reliability for the production line.
