The adaptive secondary concept has been introduced by Piero Salinari (Osservatorio Astrofisico di Arcetri - Florence) in 1993. The adaptive deformable mirror is currently one of the most attractive adaptive correction technologies for present and future telescopes.  

From the beginning, Microgate has been one of the major contributors to the development of the "contactless" adaptive mirror concept, having conceived and realized a fully dedicated control electronics that is currently at its third generation.
