Techniques are described in this paper  including the bonding procedure of silicon carbide to form a mirror shape  the CCOM technology for aspheric grinding  polishing on a home-developed tool -FSGJ-2  and the aspheric profilometry. A specialized Offner Null lens is also developed to measure the aspherical mirror with laser interferometer. With the technology depicted in the paper  a 502mm 298 mm off-axis SiC aspherical mirror is successfully made with a surface accuracy better than 1/50rms  the final result meets the design requirement.

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.   Tribological Characterization of Several Silicon-Based Materials Under Ionic-Liquids Lubrication 期刊论文 2010, 2010 Xie, Guoxin; Wang, Quan; Si, Lina; Liu, Shuhai; Li, Gang 收藏  |  浏览/下载：3/0 Design, fabrication and experiment of a heating resistor in silicon-based micro-resistojet 期刊论文 2010, 2010 Tang Fei; Wang Xiaohao; Ye Xiongying; Zhou Zhaoying 收藏  |  浏览/下载：3/0 Study on the properties of AlF/sub 3/-MgF/sub 2/-SiO/sub 2/ system low temperature co-fired oxyfluoride glass-ceramics 期刊论文 2010, 2010 Wang Rui; Zhou Ji; Li Long-tu; Li Bo 收藏  |  浏览/下载：6/0 High temperature oxidation behavior of Ti3SiC2-based material in air 期刊论文 Acta Materialia, 2001, 卷号: 49, 期号: 20, 页码: 4347-4353 Z.
