Abstract

The surface figure precision of the primary mirror in a large-aperture telescope is a key factor to the imaging quality. With the finite-element software, the finite-element model is set up base on optimization of the lateral support system. When the primary mirror is supported in the vertical position, the surface figure deformations of the primary mirror were analyzed. The rigid body displacement is removed, the max deformation of the mirror face is 261nm, the surface figure deformation RMS value is 64.03nm, PV value is 251.03nm. The results may offer some important references for the designs in this area.
