Luminaire and lamp measurement
For measuring large luminaires, the series of our type-C luminaire goniophotometers have been designed. Due to a maximum size of the measurement object (diameter) of 2000 mm, the RiGO801 – 2000 goniophotometers allow all common types of ...
Measuring ray sets
Ray sets / ray files describe the complete radiation characteristic of a light source and are often used for simulating optical components. For measuring the ray data of SSL sources and lamps, the smaller goniophotometer models have been designed.
Measurements according to the Zhaga standard
The photometric specifications of the Zhaga consortium require the luminous flux and intensity measurement as well as the evaluation of image-resolved luminances. Thus, it can be said that the RiGO801 near-field goniophotometers are ideally suited ...
The extension of a RiGO801 goniophotometer by a spectroradiometer to a goniospektroradiometer allows the measurement of color characteristics of SSL products (color coordinates, CRI, ...) according to LM79 and EN13032-4.
Correction of spectral mismatch
Since the integral parameter f1' of the photometer provides no indication of the uncertainty of the luminous flux for specific spectral power distributions, the spectral correction factor must be taken into account.
