Goniophotometers

Mangal Instrumentation offers Goniophotometers. These are rotating luminaries moving mirror instruments to achieve measuring way A- (, B (, C (-. The measurement parameters include spatial intensity distribution, intensity distribution curve of each side (represent by right-angled coordinates or polar coordinates), spatial ISO intensity curve, ISO illuminance distribution curve on the plane, luminance limitation curve, zonal flux, glare grade, luminarie efficiency, effective beam angle, upward and downward luminous flux ratio, total luminious flux, utilisation factor, electric parameters (voltage, current, wattage, power factor) and etc. of luminaries for road lighting, room lighting and projecting lighting, reflector lamps, etc. It meets the requirement of CIE, IESNA and GB and other international standards.
