GPM-1800B centric rotating reflector goniophotometer

goniophotometer It is used to test the spatial light intensity distribution as well as variety luminosity parameters of lights.

goniophotometer

1. Rotations of test samples around both vertical and horizontal axis,and rotation range:

    ±180° (or 0-360°) 2. The testing methods of single strut drive C-γ coordinate system or double strut drive

    B-β coordinate system3. Special collimation device with laser cross line, expediently and truely fix the position of    the test luminaires.4. Using technical and high level redirector which is made up by noble metal,no winding,    Intelligent start and stop keep the moving very stable,speedy and low noise.5. The accuracy of angle :0.1° , Resolution of angle :0.01°6. Accuracy of photometry CIE class A (standard class)7. The tested data meets the international and national standard requirements.IESNA file format    output can be transfered by other illumination and luminaire design software.8. RS-232C standard interface and windows operating boundary surface with both Chinese and    English,convenient to connect with all kinds of computers

9.Test distance from 2m to 30m is adjustable.
