Abstract: The invention relates to a controllable lens with variable optical power. The lens comprises a first and second cover members (111, 112), a transparent, deformable, non-fluid body (105) sandwiched between the first and second i transparent cover members, so that the first and second transparent cover members and non-fluid body constitute a lens, one or more actuators arranged to provide displacement in a direction along the optical axis, and one or more elastic elements (130, 130_1, 130_2) connecting the actuator displacement elements with the first cover member, wherein at least a portion of each of the one or more elastic elements is arranged to deform elastically in response to a relative radial displacement between the first transparent cover member and the actuator displacement elements. A first stiffness in a radial direction of each of the one or more elastic elements is smaller than a second stiffness in the direction of the optical axis of each of the one or more elastic elements.

Abstract: The invention relates to a tunable lens where the optical power can be adjusted. The lens consists of a deformable, non-fluid lens body sandwiched between a thin, flexible membrane and transparent back window, and an actuator system serving to change the overall shape of the membrane and lens body. The membrane is pre-shaped to have a Sag or Sagittal of at least 10 ?m so that the lens has a non-zero optical power when the actuator system is not activated. In order to achieve a large optical power range for the lens, the membrane should preferably be made of a material having a Young's modulus in the range 2-1.000 MPa.
