Adaptive optics: description of available components at Laserdot

LASERDOT has acquired a wide experience in Adaptive Optics Systems: components and hardware manufacturing, dedicated software, system integration and maintenance. Associated with several research organizations, it has taken advantage of having installed the first AO systems routinely used by astronomers. This paper presents deformable mirrors as well as tip- tilt mirror designed and achieved at Laserdot jointly with Observatoire de Paris-Meudon. Some comparisons between the different types of deformable mirrors are done.
