This paper represents a technique to produce the large size optical aspherical mirror by using reaction-bonded silicon carbide to meet the material requirements of the space used mirrors  based on the characters comparison of all types mirror material. 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.

This paper introduces the infrared optical system in the Tokamak fusion reaction device. In this optical system  3.the relay group lenses. This paper describes the decrease of the modulation transfer function (MTF) when the temperature changes and how to compensate the decrease of the MTF in order to maintain the image quality in a high level. As a result  the traditional optical structure can't meet the requirements  2.the Cassegrain system  the image quality of this optical system can reach the requirements when the temperature changes. 2011 Copyright Society of Photo-Optical Instrumentation Engineers (SPIE).  because the length of the infrared optical system in the Tokamak is very long. The design of optical system in the detection facility includes three parts:1.the combination of the concave aspheric mirror and flat mirror
