Gonioreflectometer
The Gonioreflectometer RiGO 801 is a dual-circle goniometer for angle-resolved measurement of the spatial scattered light distribution of an illuminated sample surface. The intensity distribution Is(Qs,j) is measured with a predefinable angular resolution in a freely definable sphere section or sphere segment with a photodiode. In addition, a luminance measuring camera can be used to measure the scattered light in a room as an intensity distribution Is(Qs,j,x,y), whereby a spatial assignment of the scattering sources on the test piece surface is possible. Different angles of incidence can be set manually via a sheet guide.
Application examples:
- BSDF measurements to characterize the scattered light behavior of rough surfaces
- Grid measurements to check shape accuracy and roughness ratio
- Conical diffraction measurements for the determination of quasi-periodic structural shapes
- Scattered light loss measurements
