IESNA GPM-1800C test system is mainly composed of GONIOPHOTOMETER, constant temperature detector, chroma detector, spectroradiometer, optical guide rail, standard lamp, angle controller, power supply and digital power meter. The reasonable selection of various measuring instruments will directly affect the overall performance, accuracy, efficiency and cost of the test system. The measured data of the system meet the requirements of international and domestic standards, like IESNA.
The file output format can be directly called by other lighting and lamp design software. The advanced commutator of precious metal optical fiber point brush technology is adopted to realize uninterrupted continuous measurement, no winding, intelligent start and stop, stable rotation and low noise.
> Photometric measurement range: 0.01lx - 99999lx
> Photometric measurement accuracy:1% (The uncertainty of the standard light source itself is not included)
> Photometric linearity: 0.2%
> Constant temperature photometric detector: Standard Class. Internal constant temperature control accuracy: ± 0.1 ℃
> Stray light: less than 0.1％
> Angle accuracy: 0.1 degree
> Angle resolution: A 0.01 degree, α 0.01 degree
>Max weight and size of the tested lamp(Including lamp and clamp)
GPM-1800C ：30kg
Length: 600mm(size of mounting base of tested lamp)
Height: 390mm(distance from the installation base of the tested lamp to the center of the light source)
> Optical path: maximum 30m
During the test, the detector is stationary and the light source rotates around the vertical axis (A-plane axis) and the horizontal axis（ α axis) to obtain the spatial light intensity distribution of the light source.
The GPM-1800C GONIOPHOTOMETER test system meets the test requirements for photometric, colorimetric and electrical parameters of the following standards
