1. Tunable prism for optical image stabilization, comprising the components:
a container that comprises a membrane comprising at least a transparent portion, the container further comprising a transparent rigid bottom portion facing the membrane, wherein the membrane is connected to the bottom portion, and wherein the container encloses a volume that is filled with a transparent fluid, a transparent window arranged on the membrane, wherein the membrane comprises a deformable portion extending around an outer edge of the window, such that the window can be tilted around a first and/or a second axis with respect to the bottom portion, wherein the window is arranged on a side of the membrane that is faces outwards the volume filled with the transparent liquid, wherein the tunable prism further comprises a prism-shaping device, wherein the prism-shaping device is in contact with the window, wherein the prism-shaping device has a clear aperture that is arranged centrally over the window, wherein the prism-shaping device is configured to tilt the window around the first and/or second axis by conveying an actuation force on the window, wherein the prism-shaping device is arranged outside the volume filled with the transparent liquid.
