Abstract

In the case of multi-point supports, this paper studies the surface of large aperture thin-mirror in different support schemes. A finite element analysis model of thin circular aperture optical components is established. The response characteristics of the surface varies by the support units' size and the support units' pitch in the frequency domain have been analyzed. According to the results, the basic principles are concluded that different size and pitch of support units should be employed based on optical system.
