Abstract
Matra Marconi Space (MMS) has designed, manufactured and tested a (Phi) 200 mm aspherical mirror to (lambda) /100 rms WFE for the purpose of a telescope demonstrator which both structure and mirrors are made from sintered Silicon Carbide. This outstanding performance has been achieved through a coordinated R and D program with the Insitut fuer Oberflaechen Modifizierung for the mastering of all the figuring aspects of any sintered Silicon Carbide telescope mirrors based on Ion Beam Figuring.
