Optimization and characterization of a light source for calibration purposes

Original language description

This study deals with a cost effective modification of a general purpose integrating sphere (IS). The aim is to create an extended uniform light source for calibration purposes focusing on matrix camera of fluorescence telescopes. Therefore, a low intensity near-UV primary light source is being used to approach the detection parameters of fluorescence telescopes. First, the radiance uniformity, which is the most important parameter, of the IS was measured in detail using an experimental setup developed in our laboratory. However, the resulting radiance uniformity of general purpose IS did not exhibit the required level, which is in general 98 %. Thus, the second step was to optimize the IS on the base of a validated optical ray-tracing model in terms of virtual prototyping. Eventually, suggested changes were implemented, the modified IS was assembled in our workshop, and finally its radiance uniformity was re-measured on the same experimental setup. The resulting radiance uniformity of the modified IS exceeds the desired 98 % and confirmed that the optimization was beneficial. This study presents methodology and results of experimental radiance uniformity measurements and introduces the modified IS for calibration purposes of fluorescence telescopes and detectors of astroparticle experiments in general.
