Abstract The high-speed polishing has become an indispensable means of spherical optical manufacture because of its process consistency and short production time. However, it is difficult to suppress deformation for optical domes with high ratio of diameter to thickness under high-speed rotation and high pressure. This limits application of high-speed polishing technology in manufacture of optical domes. In this paper, a modal analysis of high-speed polishing process for the optical dome with high ratio of diameter to thickness is demonstrated. Furthermore, a topological optimization of structure of the receipt is proposed and a series of experiments shows that the deformation cause by polishing process can be suppressed effectively.
