Goniophotometers
gonio'2pi enables the professional and precise measurement of light source and luminaire characteristics (source imaging goniometer) as well as the scatter behavior (BSDF measurements) of materials and surfaces combined with a very high measurement dynamics. The goniometer is available in a source imaging (si) configuration, a scatter measurement configuration (bsdf) and in a complete version combining both approaches. si can be easily upgraded to bsdf or vice versa at a later stage. Compared to similar devices the opsira goniometers benefit from their very robust construction paired with a very high precision in the mechanical setup.

What is Goniophotometer?
A goniophotometer is a specialized instrument designed for the precise measurement of light emitted by an object across various angles. With the rising prominence of LED light sources, which often emit directed light with non-uniform spatial distribution, the use of goniophotometers has become increasingly prevalent. These devices are crucial for assessing the angular distribution of light, especially in applications where strict regulations govern spatial light distribution, such as automotive lighting design. Goniophotometers play a pivotal role in quantifying luminous flux, analyzing luminous intensity distribution from sources smaller than the apparatus, and evaluating color temperature and uniformity through integration with color sensors.
