Abstract

See full text

The invention relates to a liquid lens (1) with an adjustable optical power comprising at least the following components:

    a lens volume (VL) with a first transparent liquid (L1) arranged between a first transparent membrane (21) and a second transparent membrane (22) opposite the first membrane (21),wherein the first membrane (21) has a first side (21-1) facing outwards the lens volume (VL) and a second side (21-2) facing in the opposite direction particularly toward the lens volume (VL),wherein the second membrane (22) has a first side (22-1) facing toward the lens volume (VL) and a second side (22-2) facing in the opposite direction particularly outward the lens volume (VL),a lens shaping element (3) arranged on the first membrane (21), the lens shaping element (3) having a circumferential aperture (3a) defining a lens area (21a) of the first membrane (21) having an adjustable curvature,a rigid transparent window element (5) connected to the second membrane (22) covering a window portion (22a) of the second membrane (22), wherein the window element (5) is circumferentially surrounded by a free portion of the second membrane, such that the window element (5) can move relatively to the lens shaping element (3) thereby bending the free portion (22b) of the second membrane (22) and adjusting a liquid pressure in the lens volume (VL), such that a curvature of the first membrane (21) in the lens area (21a) and therefore the optical power of the lens (1) is adjusted.
