English: Circular aperture, corrector ring, camera with photomultipliers that collect the fluorescence light reflected by mirrors. Optical system of a fluorescence telescope of the Pierre Auger Observatory. Malargüe, Mendoza, Argentina. English: Fluorescence detectors (FD) measure the longitudinal profile of an air shower in a calorimetric way. The FD of the Auger Observatory is composed of four observation sites, called `"eyes'". Their names are Los Leones, Los Morados, Loma Amarilla, and Coiheuco. Each eye consists of six independent telescopes. The optical system is composed of a filter at the entrance window of each FD telescope, a circular aperture, a corrector ring, a mirror and a camera with photomultipliers. |
