| Zusammenfassung | At the Physikalisch-Technische Bundesanstalt (PTB), the National Metrology Institute of Germany, a new robot-based gonioreflectometer for measuring radiance factor and BRDF has been set-up. The facility enables measurements of the directed reflection characteristics of materials with arbitrary angles of irradiation and detection relative to the surface normal. A Multi angle gonioreflectometer can be constructed either classically where several rotation and translation stages are assembled in order to achieve the desired degrees of freedom or using a robot as a sample holder for the device under test. It is expensive to stack several rotation and translation stages with lots of motor control units. We estimated the threefold price for such an arrangement. For economical reasons, we selected the robot solution. The gonioreflectometer facility consists of three major parts. A large rotation stage carrying the irradiating lamp, the 5-axis-industrial-robot as a holder for the sample under test, and the detection system consisting of a mirror-based imaging system and a monochromator for the spectrally resolved detection of the reflected radiance of the sample. |
