Abstract
A construction for a deformable mirror is disclosed in which permanent magnets are used to both retain actuators used to selectively deform the faceplate's reflecting surface within the mirror's base and to retain the mirror's faceplate to each of the actuators. The faceplate may be removed from the base by rotating each of the actuator's within its mounting hole to disrupt the magnetic circuit between each actuator and ferrous elements on the faceplate. Removal of one or more actuators from the base without disturbing the faceplate may be effected by rotation of the actuators to be removed to disconnect magnets in plugs used to support each actuator within the base from ferrous elements in the base.
