The entire spectrum of angle-dependent measurements

The goniophotometers from Instrument Systems allow angle-dependent optical parameters of LED and SSL products to be comprehensively analyzed. This covers the entire value chain from single packaged LEDs, through LED modules and light engines to large SSL lamps and luminaires.

All goniophotometers are designed as Type C with a horizontal alignment of the optical axis (turning luminaire configuration). Each goniometer sets benchmarks in its class for precision, reliability and handling. If these goniophotometers are combined with a spectroradiometer from Instrument Systems, they are able to determine not only photometric data but also spectral quantities, such as color coordinates, color temperature, and even color rendering index as a function of angle.
