Abstract

The invention relates to a focus-tunable liquid lens (100) comprising a container (6) filled with a transparent liquid, wherein the container (6) comprises container components: a) an elastically deformable transparent membrane (4) arranged on a first side of the container (6), b) a transparent window element (5) arranged opposite the membrane (4) on a second side of the container (6), particularly wherein the window element (5) forms a transparent bottom portion of the container (6), c) an elastically deformable circumferential wall portion (1) connecting the window element (5) and the membrane (4) along a contour of the wall portion (1), the wall portion (1) limiting a radial extension of the container (6) along a radial direction of the lens (100), d) a lens shaping element connected to the membrane (4), wherein the lens shaping element has a circumferential aperture comprising an optical axis (OA) of the lens (100), wherein the aperture encloses a lens area of the membrane (4) within which a shape of the membrane (4) may be adjusted by actuating the lens shaping element relative to the window element (5) by means of an actuation force for adjusting a refractive power and/or other optical properties such as astigmatism, a prism and/or another optical aberration of the lens, wherein the wall portion (1) is formed as a bellows, particularly such that upon actuation of the lens shaping element the radial extension of the container (6) is maintained or at least reduced.
