robogonio BSDF

Module for fast spectrally resolved scatter light measurement

Current developments in photonics use new materials to combine light conversion and light scattering. High power density, small dimensions and the mutual influence of conversion and scattering make a simulation of light conversion and light scattering impossible. Spectrally resolved scattered light measurements are a crucial prerequisite for the development of even more efficient light sources.

The standard measurement method for determining the BSDF (bidirectional scattering distribution function) / BRDF (bidirectional reflectance distribution function) is goniophotometry. The sample is mounted on a specimen fixture. Lighting and a detector are positioned relatively around the sample. Scattered light goniophotometers have a complex and expensive setup and are slow. In the project, a new, fast and cost-effective solution for scattered light measurement was developed. Thus, a new module is added to the proven opsira robotic goniophotometer (robogonio) to enable fast and cost-effective spectrally resolved scattered light measurements.

The robogonio is a very versatile system to realize the relative solid angles and distances between the DUT (luminaire, lamp) and the detector system required for photometric measurements in a very wide range.

The aim of the project was to develop an additional module for the robogonio, which realizes the need of at least 2 more axes without an additional device, but as an additional "claw" attached to the robogonio.  

The new robogonio BSDF will be presented during the next Light+Building Tade Show from October 2nd to 6th, 2022 in Frankfurt/Main in Germany, opsira Stand F70 – Hall 8.0.

This Project is supported by the Federal Ministry for Economic Affairs and Climate Action (BMWK) on the basis of a decision by the German Bundestag.
