HPG2000 is a C-type goniophotometer. It uses a reflector that moves in a circle around the center of the test lamp to reflect the light beam in the measurement direction of the lamp onto the photometric detector to measure light intensity distribution curves on different planes.
The illuminance integration method recommended by CIE can be used to achieve the highest precision measurement of the total luminous flux of various lamps and light sources. This method is used in photometric laboratories in major developed countries to achieve the national benchmark for total luminous flux. It can realize the spatial color distribution, average color characteristics and spatial non-uniformity measurement of various light sources and lamps. It can also realize the measurement of spatial brightness distribution of various light sources.
