Adoption of a movable mirror achieves stable measurement of the light distribution toward all angles without tilting a light source.
In this goniophotometer, the tested luminaire rotates in the prescribed burning position and around the vertical axle and a reflecting mirror rotates around the horizontal axle, meanwhile, a synchronous axle will rotate toward the opposite direction synchronously. The combined motion of the luminaire and mirror permit luminous measurement at the direction of any horizontal or vertical angle without tilting the luminaire, therefore, the luminous intensity will be not variation. The photometer head located at a fixed position of the limiting photomet- ric distance in front of the reflecting mirror to gather the light in each direction.

C-γ coordinate system photometry corresponds to JIS C8105-5 standard, satisfies the requirements of US Energy Star criteria of IESNA LM-79-08 on the optical properties and electrical LED lighting and CIE 70 recommended structure possible.
It is suitable for the measurement of photometric parameters and other spatial intensity distribution by the method of fixing the light source which a reflector rotates around, particularly floodlighting, road lighting, and indoor lighting.
It is also possible to install photometric detector, the chromaticity detector, in order to measure the non-uniformity of chromaticity and photometry.
