摘要： The present invention relates to an Optical zoom device (1), comprising a first lens (10) having an adjustable focal length and a second lens (20) having an adjustable focal lens, wherein each lens (10, 20) comprises a lens core (11, 21) filled with a transparent fluid (12, 22), wherein the respective lens core (11, 21) comprises a first wall (13, 23) in the form of an elastically deformable membrane and a transparent second wall (14, 24) facing the first wall (13, 23), wherein the fluid (12, 22) is arranged between the two walls (13, 23; 14, 24) of the respective lens core (11, 21), and wherein the respective lens (10, 20) comprises a lens shaping member (15, 25) interacting with the respective membrane (13, 23) for adjusting the focal length of the respective lens (10, 20) and/or for stabilizing an image generated with help of the two lenses (10, 20), wherein the optical zoom device (1) comprises a first and a separate second lens barrel (30, 31), wherein the first lens core (11) is mounted on the first lens barrel (30) and the second lens core (21) is mounted on the second lens barrel (31), wherein the optical zoom device (1) comprises at least one actuator (40) associated to the first lens (10) for generating said interaction of the lens shaping member (15) of the first lens (10) with the membrane (13) of the first lens (10) for adjusting said focal length of the first lens (10), as well as at least one actuator (41) associated to the second lens (20) for generating said interaction of the lens shaping member (25) of the second lens (20) with the membrane (23) of the second lens (20) for adjusting said focal length of the second lens (20).
