Our characterization tool, called METHOD which was previously built for refractive optics [1], has been adapted and optimized to evaluate a mirror from the APOLLON Project [2], characterized in the framework of the European CPVMatch project. Influence of the glass box of the thermal chamber, homogeneity of the temperature across the sample, and influence of the chromatic light on the energetic spot’s center are studied. We evaluate the mirror’s abilities at different working temperatures and cell-to-primary optical element (POE) distances.
