Abstract

See full text

The invention relates to an optical device (1), comprising: at least a first lens (100) having an adjustable focal length, wherein the first lens (100) comprises a container (2) comprising at least one reservoir volume (90) and a lens volume (91) which are in flow communication via a channel (92) and filled with a transparent fluid (F), and wherein the container (2) comprises a stretchable transparent membrane (21) and a transparent lens shaper (22) that is immersed in the fluid (F) and connected to the membrane (21), so that the lens shaper (22) defines a curvature-adjustable area (23) of the membrane (21), and wherein the container (2) comprises a transparent back wall (30) facing the membrane (21), wherein the fluid (F) is arranged between the membrane (20) and the back wall (30). According to the present invention, the at least one reservoir volume (90) is covered by a wall (21), wherein a plunger (94) for interacting with an actuator part (e.g. an electropermanent magnet (80)) is arranged in the at least one reservoir volume (90) and connected to the wall (93) so that fluid (F) is pumped from the lens volume (91) into the at least one reservoir volume (90) when the plunger (94) is attracted h the electropermanent magnet (80) whereby the curvature of the curvature-adjustable area (23) and therewith said focal length is changed.
