GO-R100 Circus Moving Mirror Goniophotometer - GO-R100

Also called Circus Rotating Mirror Goniophotometer.

It was widely applied in industry and laboratory in the past 40 years.

It overcomes the problem of the stability of the tested light source.

But there still some unsolvable problems.

Specifications
This kind of goniophotometer is also called Circus Rotating Mirror Goniophotometer. it keeps the tested light source stable at the center and the reflecting mirror rotates around the tested light source.

1.Technical characteristics.
It overcomes the problem of the stability of the tested light source.
But there still exists the following unsolvable problems:
The incident angle of the measured principle light to the detector was strictly limited by CIE 70-1987. It will lead to a very long dark room space. It will be very difficult to measure the small and low intensity level light sources at such a long distance for sensitivity of the photometer.
The larger view angle of the detector will be very difficult to avoid the incidence of stray light.

2.Powerful measuring functions
Luminous intensity data, luminous intensity distribution curve, efficient luminescence angle, spread angle, zonal luminous flux, luminaires efficiency, total luminous flux, upper luminous flux, lower luminous flux, available average illuminance curve, coefficient of utilization, luminance limitation curves, glare, maximum ratio of distance to height, iso-Illuminance diagrams, curves of luminaires

vs lighting area, Isocandela diagrams etc.
