Luminance meter GA-500M

The GA-500M and GA-1200M glare analyzer is respectively equipped with 5 megapixel and 12 megapixel resolution detectors and 180 fisheye lens, effectively providing two indicators for CIE 117-1995: 1.UGR test is suitable for light sources with a stereo angle of 0.1~0.0003sr, so the resolution of the imaging photometer must be greater than 5 million pixels to ensure accurate measurement of 0.0003sr light source; 2.The maximum value of T/R in the Guth position index table is 3, so the FOV of the test system must be greater than 2×arctan3=143.14°. The GA-2600 adopts Canon's 26-megapixel full-frame, high-resolution detector SLR camera, equipped with an 8mm fisheye lens or standard lens for indoor, outdoor, and road glare analysis. Equipped with a Y filter that approximates human eye visual function. The multiple exposure and ND filter can meet the wide measurement range, achieving up to 1000,000:1 contrast test. Cooperated with professional glare analysis software, multi-point luminance data can be obtained in one photo, and the glare value can be calculated. Support readout of ROI.
