The optical performance of the MAGIC-II telescope — •Cornelia Lühmann, Florian Göbel, Ralf Kosyra, and Jürgen Hose for the MAGIC collaboration — MPI for physics, Munich, Germany

The optical performance of the mirrors for an imaging Cherenkov-telescope is of great importance since they are the first element of the detection chain. Optical parameters like the PSF (point spread function), the reflectivity and the focal length play a great role. Measurements were performed to determine those parameters for the mirrors of the MAGIC-II telescope on La Palma. In this presentation the measurement principles will be described and the results for the optical parameters of the mirrors shown.
