VDU-1160-20 2D Spectral Imaging Colorimeter

The VDU-1160-20 is a next generation family of 2D spectral imaging colorimeters combining the strengths of a CCD image sensor and high performance spectroradiometer. This results in a rapid and highly accurate system for display measurements including luminance, correlated color temperature (CCT), CIE chromaticity and uniformity. The system is particularly well suited for test and characterization of LCD, LED and OLED displays. Laboratory grade accuracy and flexibility are combined with high speed and durability for demanding production environments.

Unlike traditional colorimeters, this next generation design eliminates the need for color filters. All aspects of system performance are improved over previous generation technology with this approach.
