Paper Abstract

The design of an adaptive secondary mirror has to satisfy many requirements coming from different fields. The thin mirror must be actuated very precisely with a large bandwidth. The reference plate has to provide a high stability reference for the optical surfaces. The local seeing is not to be degraded by any significant thermal perturbation. In this article, the performances of a configuration with a single aluminum reference plate, that also provides the heat sink, are computed starting from the input power coming from the magnetic actuators, whose magnetic design has been revised.
