Photometers & Colorimeters
Instrument Systems Optische Messtechnik GmbH
A photometer is used to measure the photometric quantities of illuminance (lx), luminous intensity (cd), luminous flux (lm), and luminance (cd/m²). The integral method and the fast response time of silicon photodiodes means that photometers can achieve an outstanding measuring speed. They are therefore ideal for performing fast goniophotometric measurements. We take great care in the development and production of photometer heads and use innovative amplifier technologies.

Goniophotometer
A goniophotometer is a system to measure the luminous intensity of the source (or illuminance from the source at a given distance) in many different directions from the source. Compared with the sphere method, the goniophotometer method is theoretically free from errors due to differences in intensity distribution of the light source under test. It is applicable to acquire the luminous intensity distribution, luminous flux, spatial color distribution, and luminance distribution of lamps and luminaires.

Goniophotometer
GMS2000
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.
