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.

Light-resistant Integrating Sphere
-
The integrating sphere is used for total luminous flux measurement. It uniforms the light by spatially integrating the collected light of light source. The integrating sphere has highly reflective diffusing plates formed on the spheres internal surfaces. These plates repeatedly scatter light rays from the light source with in the sphere to all other points to deliver uniform brightness distribution so measuring a portion of that light gives the total luminous flux. These years, the usage of integrating sphere for total luminous flux evaluation of light source is increasing. The large size integrating sphere over 1.5M is required for measuring a high brightness light source and a long light source such as fluorescent light.

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.
