Active optics for high-dynamic variable curvature mirrors
arXiv:1411.4807 · doi:10.1364/OL.34.003009
Abstract
Variable curvature mirrors of large amplitude are designed by using finite element analysis. The specific case studied reaches at least a 800 μm sag with an optical quality better than λ/5 over a 120 mm clear aperture. We highlight the geometrical nonlinearity and the plasticity effect.
