The goniometers of opsira GmbH record angle-dependent photometric parameters around a light source, a luminaire, a detector or a material sample. The robust Goniospectroradiometer construction as well as the direct drive concept introduced and consistently implemented by opsira GmbH guarantee a very high precision of the goniometer systems. Photometers and radiometers, the luca luminance measuring systems, the spectral measuring systems spec'3 and spr'3 as well as high-quality photomultipliers are available as Goniospektrometer detectors.
opsira's ultimate goniophotometer and goniospectrophotometer solution is called robogonio. The highlight: a goniophotometer on a freely configurable, fully flexible KUKA robot arm.Through their innovative design the Goniospectrometer can be adapted to your situational and specific requirements.
With the gonio'2pi Gonioradiometer you can professionally and precisely measure light source and luminaire properties (near-field photogoniometer) as well as scattering behaviour (BSDF measurements) of materials and surfaces with very high measurement dynamics. The goniometer is available in a near-field configuration (si), a scattered light configuration (bsdf) and in a complete version for both applications. A later Gonioradiometer upgrade from si to bsdf or vice versa is easily possible. The spectrum of the unique gonio'2pi thus ranges from the smallest light sources to large luminaire systems as well as the Gonioradiospectrometer analysis of material properties.
