A deformable mirror assembly is provided employing a pressure differential across the mirror element to flex the mirror into a configuration. The configuration is determined by an array of positioning members, each having a fixed back end and a movable front end. The invention employs long-stroke electromagnet actuators with built-in position sensing.

[ What is claimed is:] [1.]1. A deformable mirror assembly comprising:a deformable mirror element having a front face and a back face and a perimeter surrounding and connecting the front face and back face;an array of positioning members, each having a fixed back end and a moveable front end, the array located behind the mirror element;wherein each positioning member comprises an actuator, comprising:a first end and a second end;a yoke fixed relative to the first end;a coil fixed to the yoke;an attractive member fixed relative to the second end and selectively attractable to the yoke via energizing the coil; andan elastically compressible member prebiasing the attractive member away from the yoke;wherein the compressible member is an elastomer molded in situ between the yoke and the attractive member.
