Paper Abstract

We present the CILAS "Piezo Array" technology for Deformable Mirrors (DMs). Its main technical advantages are high order, large stroke, large bandwidth, high optical quality and very low dependence to temperature and environment. This technology can lead, on one hand, to very high order (several thousands), small inter-actuator spacing (1 mm range) DMs and, on the other hand, to large aperture DMs (2.5 m range). Both are needed for next generation of instrumentation and Extremely Large Telescopes (ELTs). A second family of DMs used for astronomy is the "Bimorph" technology. This piezo technology also allowed to obtain very good results on the most famous telescopes in the world.
