GMS-3000 Moving Mirror Goniophotometer with Pursuit Detector

GMS-3000 moving mirror goniophotometer with pursuit detector is one of the mirror goniophotometers recommended in ClE No. 70, and meets requirements of IESNA LM79. In this system, the position of tested luminaires is fixed and the mirror rotates around the photometric center of the tested luminaire. The pursuit detector and rotating barrier rotates synchronously with the mirror to ensure the light beam always be reflected into the detector perpendicularly and to eliminate the stray lights. The CCD spectrometer and photodetector installed in the center of the light trap could measure the spatial luminous intensity distribution, total flux and chromaticity uniformity of small size lamps. The pursuit detector and chromaticity measuring system are used to measure spatial intensity distribution of large size luminaires, narrow beam luminaires and high intensity indoor/outdoor luminaires and lamps, meeting the requirements of Energy Star, NVLAP, ERP, ESP.
