Abstract:
The present invention is related to a lens assembly comprising a flexible lens body (10) inside a cavity bounded by a sidewall (11) and a first transparent cover (13), and a second transparent cover (14), wherein both covers (13,14) are in contact with respective surfaces of the lens body (10). Piezo electric elements (12) shapes the lens body (10) when activated, thereby adjusting the focal length of the lens assembly.
