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.
