Paper Abstract

To realize the rapid repairing of surface damage of fused silica optics, a method combining magnetorheological and Computer controlled optical surface (CCOS) was proposed to quickly remove small size damage points on the surface of damaged fused silica optics. In this paper, the size and number of damage points on the surface of fused silica optics are analyzed. Meanwhile, the surface of the fused silica optics is evenly removed by the magnetorheological technology, and the change rule of damage points on the surface of fused silica optics is analyzed. After that, CCOS smoothing technology is used to restore the surface quality of the optics. The experimental results show that the combined technology can effectively remove the small size damage points on the surface of fused silica optics and maintain the surface quality of the optics, achieving a good repair effect.
