GPM-2000 centric rotating reflector goniophotometer

goniophotometer It is an automatic light distribution testing sysytem.It can measure all types of lighting sources and luminair

goniophotometer

1. Measure luminous intensity data,luminous intensity distribution,zonal luminous flux,luminairesefficiency,luminance distribution,coefficient of utilization,luminance limitationcurves,glare,maximum ratio of distance to height,equal illuminance diagrams,curves of luminaires vs lighting area, isocandela diagrams,efficient luminescence angle etc.

2. The tested luminaire rotates around the mirror with an angle of (γ)±180°°or 0-360°,andthe tested luminaire rotates around itself with an angle of (C)±180°or 0-360°).

3. Using technical and high level redirector which is made up by special metal fiber,no winding, interllective startup and stop ,keep stable rotating continuous testing and low noise.

4. The position and working state remain the same as it is under working

5. Special collimation device with laser cross line,convenient and accurately fix the position ofthe tested luminaires.

6. The accuracy of angle :0.1° , Resolution of angle :0.01°.

7. Accuracy of photometry : CIE class A (standard class).

8. The tested data meets the international and national standard requirements.IESNA file format output can be transfered by other illumination and luminaire design software.

9. RS-232C standard interface and windows operating boundary surface with both Chinese and English,convenient to connect with all kinds of computers.
