The Gravity Effect of Mount Design on the Mirror Optical Aberration

Abstract:

Optomechanical analysis and design approaches for development of large mirror mount are presented in this article. The relationship between mirror optical aberration and gravity effect is studied for difference mirror mount designs. A detailed structural analysis of mirror mount design using finite element model combined with Zernike polynomials fitting is found successfully to predict optical aberration in the Cassegrain optical system.
