Abstract

This paper describes the application tendency of beryllium mirror of space astronomical instruments and the tip-tilt mirror of the correlation tracker of a Space Solar Telescope (SST). The optimization choice of tip-tilt mirror substrate material, the light-weighted scheme of tip-tilt mirror substrate, the analysis and optimization design of mirror structure were accomplished. At last, the final RMS surface figure error of 2.18×10^-6mm and PV of 1.69×10^-5mm were obtained with resonant frequency of 1609Hz, and the mass of the beryllium mirror of 47.88g. These results satisfy the technology requirements of the tip-tilt mirror of the correlation tracker. The manufacture technology of beryllium mirror substrate, the nickel plating technique on beryllium mirror substrate and optical fabrication were discussed in detail.
