Goniophotometer
GMS2000 - OptCom Company, Ltd
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.
