The deformable mirror is the single most expensive component in atmospheric correction systems of 100 actuators or less. An innovative design for a membrane mirror is proposed as a cost effective alternative to conventional deformable mirrors. The mirror features a high voltage (250v) bias on the mirror surface, which eliminates many of the disadvantages of past membrane mirror designs. The High Bias Membrane Mirror provides a rugged, reliable, inexpensive unit suitable for low power, low density wavefront correction systems. As such it is ideal for compensated imaging systems for surveillance and astronomy, which may require only partial compensation.
