Functions:To meet the requirements of the structure recommended in CIE No.70 and US Energy Star standard for SSL LM79-08, the goniophotometer could measure the light distribution with C-Y coordinate system while the luminiare position is fixed and mirror rotates around luminaire. It is suitable for the measurement of the spatial intensity distribution and all of the photometric parameters of indoor lightings, flood lightings and road lightings. The detector platform could install the photoheader and color detector to measure the spatial uniformity of photometry and chromaticity. Specifications: >> Thermostatic Photodetector V() accuracy: CIE-f1'less than 0.015 Photometric resolution:0.00001lx, 0.0001lx, 0.001lx (Optional) Thermostatic Temperature:35˚C >> Angle accuracy: 0.1 degree >> Driving Angle Resolution:Y angle is 0.0016 degree C angle is 0.03 degree >> Capacity for tested luminaries Power: AC/DC 600V/10A x 6 lines Dimesions of max luminaires: M(1.0),S(0.6m)(Customized)
