GPM-3000 Goniophotometer is a highly intelligent light distribution performance testing system. It can measure all types of lighting source and luminaires.(Such as Indoor and Outdoor luminaires, Street luminaires, Flood lamps, etc) with high accuracy. It can achieve the test methods of CIE C-γ, CIE B- β and CIE A-α.The tested results can be directly used by international lighting design software like Dialux. It meets and requirements of CIE and IESNA standards.

>The tested data must meet the requirements of international and national standards, IESNA file format output can transfer other lighting and lamps and lanterns design software
>RS-485 standard interface, convenient to connect with various micro computer, standard English/Chinese operator interface, meets the international requirements
>Tested lamp position and the actual use state are the same, lamps working condition is unchanged
>Special laser cross line aiming device, be convenient and accurate to install the tested lamps and lanterns
>Advanced commutater which adopts the precious metal optical fiber dot brushing technology, can achieve continuous test with the advantages of no winding, start and stop intelligently
smooth rotation and low noise
1) The mirror rotates around the tested luminaire with an angle of (γ)±180°（or 0～360°）,and the tested luminaire rotates around itself with an angle of (C)±180°（or 0～360°).The detector
rotate with mirror synchronously or rotate around the tested luminaire (0-360° )
2) Using high level redirector made up by special metal fiber, no winding, intelligent startup and stop , keep stable rotating, continuous testing and low noise.
3) The position and working state remain the same as it is under test. Laser cross line aiming device to ensure fixing the test lamps accurately and conveniently.
4) The accuracy of angle :0.1° , resolution of angle :0.01°.
5) The accuracy of photometric:standard class.
6) The tested data meets the international and national standard requirements.Test result can be output with IES,IDT,CEN, CIB,CSV.TM4,CIE files and directly used by design software like Dialux.
