Patent ID: 6942352

Claim:
A transfer optical surface of graphite filled cyanate ester composite comprising: A. A mirror made of said graphite filled cyanate ester composite of preselected thickness and shape with a reflecting surface and a back surface, said mirror having a preselected coefficient of expansion; B. a support made of material with the same coefficient of expansion as said mirror for holding said mirror; C. a sealant placed to hold said mirror in said support such that it forms a bond between said mirror and said support; D. a plurality of push-pull rods mounted to said mirror back surface in a predetermined pattern; E. a plurality of actuators, one operably connected to each of said plurality of push-pull rods; F. a master control connected to all of said actuators so they may be individually activated independent of the remaining actuators; and G. an actuator mounting plate made of material with the same preselected coefficient of expansion for supporting said plurality of actuators.
