Paper Abstract

In total, more than 500 X-ray mirrors have been produced by Media Lario for the assembly of the six XMM telescopes. The x-ray performance of the individual mirrors has been evaluated both in terms of mirror shape and surface quality with the help of several metrology devices. In this paper we will present first eh metrology operations which were applied on the XMM mirrors to product their optical performance. Then, the metrology result will be analyzed and compared to the performance obtained during the verification and calibration campaigns. Finally, from the large XMM experience, we will conclude by giving some recommendations on the metrology tools to be used for the prediction of the performance of the next generation of x-ray telescopes.
