Query: Active optics for high-dynamic variable curvature mirrors   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.
