Abstract: A system for fastening a mirror to a support is disclosed including intermediate structures, for example bipod structures. At least some of the intermediate structures are provided with torsion devices making it possible to at least partially compensate for optical aberrations of an instrument that includes the mirror. Each torsion device may comprise an elastic element and a variator. The variator is designed to control a deformation of the elastic element, resulting in a torque which is applied to the mirror.
