GPM-1600L Goniophotometer(Economic Type)

GPM-1600(L) goniophotometer is composed of host,controller and detector, It can realize measurement of light intensity in all directions, color spatial uniformity, average color features and spatial color non-uniformity of light source and lamps. 

Tested parameters are the same as GPM-1800B.

Measurement method

It can also realize B-β and C-γ measurement under CIE standards.

Characteristics

○ Tested luminaire rotates around  both vertical and horizontal axis and rotation range is:±180°(or  0～360°).

○ Single arm for C-γ measurement. Double arms for B-β measurement.

 ○ Using high level redirector made up by special metal fiber, no winding, intelligent startup and stop , keep stable

    rotating,continuous testing  and low noise.

○ The accuracy of angle :0.2° , resolution of angle :0.01°.

○ The accuracy of  photometric:standard class.

○ The tested data meets the international and national standardrequirements.Test result can be output with IES,IDT,

   CEN,CIB,CSV.TM4,CIE files and directly used by design software likeDialux.
