Abstract

This poster shows the design, and the indoor validation of 'DUSST' (Detector Unit for Soiling Spectral Transmittance), a new low-maintenance soiling station. DUSST projects a collimated monochromatic light through a glass surface and on to a light detector to measure the intensity of the transmitted light. As the glass surface naturally soils, the losses are quantified by comparing this soiled reading with a calibrated reading in the baseline clean condition.
