1. A liquid lens 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 and a second transparent membrane opposite the first membrane,
wherein the first membrane has a first side facing outwards the lens volume (VL) and a second side facing in the opposite direction, a lens shaping element arranged on the first membrane, wherein the lens shaping element has a circumferential aperture defining a lens area of the first membrane having an adjustable curvature,
wherein the second membrane has a first side facing toward the lens shaping element and a second side facing in the opposite direction, a rigid transparent window element connected to the second membrane, wherein the window element is circumferentially surrounded by a free portion of the second membrane, such that the window element can be moved relatively to the lens shaping element,
wherein the lens volume (VL) forms or comprises a first volume (V1) comprising the first liquid (L1), and
the lens comprises a second liquid (L2) in a second volume (V2), wherein the second volume (V2) is arranged at least partially on the optical axis (OA) of the lens, particularly along the z-axis of the lens, wherein the first liquid (L1) and the second liquid (L2) as well as the first volume (V1) and the second volume (V2) are separated from each other by a separating membrane portion.
