Tunable non-round fluidic lens with immersed lens shaper

An optical device, comprising:

• at least a first lens having an adjustable focal length, wherein the first lens comprises a container that defines a volume which is filled with a transparent fluid, and wherein the container comprises a front wall, which front wall comprises a transparent membrane that is flexible and stretchable and a transparent lens shaper that is immersed in the fluid and connected to the membrane, so that the lens shaper defines a curvature-adjustable area of the membrane, and wherein the container comprises a back wall facing the front wall, wherein the fluid is arranged between the front wall and the back wall, and wherein the back wall forms a lens, the optical device comprises an actuator means which is configured to adjust said volume of the first lens in order to adjust the curvature of said curvature-adjustable area, wherein adjusting said volume comprises compressing a portion of the volume so that the liquid contained in the volume presses against the membrane and thereby adjusts the curvature of said curvature-adjustable area, and/or wherein adjusting said volume comprises expanding a portion of the volume so that the fluid presses less against the curvature-adjustable area of the membrane and thereby adjusts the curvature of said curvature-adjustable area, and the actuator means comprises at least one electropermanent magnet and at least one magnetic flux guiding counter member attractable by the electropermanent magnet for adjusting said volume of the first lens in order to adjust the curvature of said curvature-adjustable area of the membrane.
