Paper Abstract

Ceramic mirrors are going to become more and more attractive for realizing lightweight optomechanical systems. The C/SiC ceramic described in this article, a joint development of DSS and IABG offers design freedom through a novel straight forward manufacturing process, combined with excellent optomechanical properties. This process not only enables to build ultra lightweight mirrors of very high complexity, but also very large 3d-structures. Mirrors up to 80 cm and structures up to 2.5 m have been realized. The paper will summarize the recent progress achieved in producing mirror blanks up to 1 m diameter and beyond. Recent results in new technologies for achieving high performance optical surfaces will be reported. An outlook for future envisaged applications of C/SiC technology, e.g. 2.5 m mirror segments for the next generation of large earth and space based telescopes, is given.
