In order to ensure the surface figure of the pointing mirror (460mm long
290mm wide) in spaceborne remote sensing camera
Silicon Carbide was selected as the mirror material. The form of composite triangular and rectangular and the combination of open and closed back was explored in the lightweight design. A new kinematic mount and flexible structure in axis is used to hold the mirror around the lateral surface. The structure can minimize distortions induced by coefficient of thermal expansion mismatch among the materials. This eliminates the bending of the integral mount under the weight of the mirror. Optical performance of the mirror was analyzed under gravity load and temperature load using finite element method. Predicted surface figure error based on the removal of bias
tilt and power was calculated using an in-house Matlab script for mirrors. The pointing mirror assembly was tested using open loop servo control. And the surface figure was checked using interferometer. Surface figure accuracy is better than 1/30 ( 632.8nm
rms). The results show that the kinematic mount induces minimal figure error on the optical surface. 2011 IEEE.

Silicon carbide (SiC) is a new type candidate material for large-scale lightweight space mirror. Its low thermal distortion
high stiffness
fine optical quality and dimensional stability
make SiC an ideal material for large space born telescope. Since ten years Changchun institute optics
fine mechanics and physics (CIOMP) has developed reaction bonded SiC (RB-SiC) technology for space application
and can fabricate RB-SiC mirror with scale less than 1.0 meter for telescope. The green body is prepared with gel-casting method which is an attractive new ceramic forming process for making high-quality
complex-shaped ceramic parts. And then unmolding
drying
binder burning out
reacting bonded
the RB-SiC can be obtained. But with the development of space-born or ground telescope
the scale of primary mirror has exceeded 1.0 meter. So CIOMP has developed an assembly technique which called novel reaction-formed joint technology for larger RB-SiC mirror blank. The steps include joining of green bodies with mixture comprised of SiC particles and phenolic resin etc
firing
machining and sintering. Joining the 1.2 meter RB-SiC mirror blank by the novel reaction-formed joint technology. And testing the welding layer's performance
the results show that the thickness of 54-77m
the microstructure and thermal property can be comparable to the substrate and the mechanical property are excellent in bending strength of 307MPa. 2010 Copyright SPIE - The International Society for Optical Engineering.
