Abstract

The Deformable Mirrors are, with the wavefront sensors, the core of the adaptive optics system of MORFEO (formerly known as MAORY), the first light AO system for ELT. Such large deformable mirrors (about convex 930 and concave 1220 mm) and the large number of modes (about 900 and 1000 modes) will allow a fitting error below 40 nm RMS on the atmospheric turbulence layers which they are conjugated to with a worst seeing case of 1.5 arcsec. In this paper we will briefly present the status of the design and the performances reached.
