Abstract
The invention relates to a mirror telescope for use in inaccessible assemblies such as in satellites. The primary mirror and the secondary mirror are made of the same material as are all components which fix and influence the distance. In this way, a mirror telescope is provided which maintains its optical characteristics without readjustment over a long period of time.
