Abstract
A deformable mirror device which includes a deformable face plate, a backing plate spaced from the deformable face plate, and at least one axially movable actuator which extends between the face plate and the backing plate. The actuator is fixed adjacent a first end to the backing plate and adjacent a second end, which is opposed to the first end, to the deformable face plate in a kinematic joint by reason of which no forces are transmitted in an ideal mating of the two components. At least a portion of the actuator may be disconnected and removed from the first end, and replaced by another actuator. The kinematic joint includes a high temperature, permanent, joint and a pair of spaced apart, low temperature, temporary joints. The high temperature joint is defined by a ball segment affixed to the deformable face plate as by frit. One of the low temperature joints is defined by an epoxy connection between the actuator at its first end and the backing plate. The other of the low temperature joints is defined by an epoxy connection between the actuator at its second end and the ball segment.
