We evaluate mirror-based and achromatic optics at different working temperatures and cell-to-primary optical element (POE) distances. The magnitude and the effect of chromatic aberration and non-uniform flux profiles are assessed under controlled testing conditions. Our characterization tool is called METHOD [1]: it is capable of measuring multi-spectral irradiance profiles of concentrator photovoltaic optical systems along with the corresponding current (I)-voltage (V) characteristics produced on a concentrator solar cell receiver. In this study, METHOD is adapted to evaluate a mirror from the APOLLON Project [2], characterized in the framework of the European CPVMatch project.
