Abstract
November 1992 the Deformable Mirror (DM) for ESO's Near Infrared Adaptive Optics System (ADONIS), was delivered with a measured specification of surface flatness better than λ/2 without voltage applied on the actuators, and better than λ/4 when offset voltages are applied such that the first 8 Zemike terms are removed(1).
