In its current implementation, the "contactless" adaptive mirror is based on a continuous , thin mirror (~1.6mm) actively controlled in position and shape by a large number of force actuators (voice coil motors). During operation, the thin mirror "levitates" controlled by the electromagnetic field generated by the actuators. There is no mechanical contact between actuators and thin mirror. Each actuator is made by a fixed coil wound on a cold finger and a moving magnet, glued to the rear surface of the thin
