Active optics for high-dynamic variable curvature mirrors

Instrumentation and Methods for Astrophysics 2014-11-19 v1

Abstract

Variable curvature mirrors of large amplitude are designed by using finite element analysis. The specific case studied reaches at least a 800 {\mu}m sag with an optical quality better than {\lambda}/5 over a 120 mm clear aperture. We highlight the geometrical nonlinearity and the plasticity effect.
