GP series evaluates goniophotometric characteristics for vehicle displays and headlights up to 2,400mm. It can handle a wide range of lighting fixtures from room lighting to floodlights and is customizable to meet your multi-purpose needs.
Up to 2,400mm of LED lightings can be measured
Compatible with vehicle displays and headlights' goniophotometric measurement
By automatically controlling a biaxial goniometer to measure spectral distribution at every angle, spectral total radiant flux, total luminous flux, chromaticity, color temperature, etc. can be obtained
The newly adopted detector has a wide dynamic range
Compliant with IESNA LM-75 and CIE121
