Patent ID: 7443619

Claim:
An apparatus for holding an optical element, the apparatus comprising: a deformable optical element having an optical surface and backside; a holder configured as a base for the apparatus; at least one non-contact type force generating actuator configured to deform the optical surface of the optical element, the at least one non-contact type force generating actuator being disposed between the holder and the backside of the optical element, wherein the at least one non-contact type force generating actuator is selectively chosen and adapted to attenuate vibration exceeding a predetermined frequency in which the vibration exceeding the predetermined frequency is capable of being transmitted through the apparatus to the optical element; a measuring device configured to measure a position of the physical location and overall positioning of the optical element as a whole; and at least one displacement causing actuator configured to position the physical location of and overall positioning of the optical element as whole, but not configured to deform the optical surface of the optical element, wherein the displacement of the physical location of and overall positioning of the optical element as a whole is based on the measured position, wherein the at least one displacement causing actuator is selectively chosen and adapted to attenuate vibration frequency lower than the predetermined frequency in which the vibration having the frequency lower than the predetermined frequency is capable of being transmitted through the apparatus to the optical element.
