Abstract
Objective comprising a lens barrel, an actuator and a tunable lens, wherein the tunable lens comprises a primary membrane and a secondary membrane delimiting a liquid volume on opposing sides along an axial direction, the tunable lens comprises a container delimiting the liquid volume in lateral directions, wherein the lateral directions extend perpendicularly with respect to the axial direction, and the primary membrane and the secondary membrane are attached to opposing sides of the container, the tunable lens comprises a window member which is attached to the secondary membrane, wherein the secondary membrane connects the window member and the container elastically, wherein relative motion of the window member and the container along the axial direction results in a change of an optical property of the tunable lens, the window member or the container is fixedly attached to the lens barrel, the actuator is arranged to provide an actuation force along the axial direction, wherein the actuation force acts between the tunable lens and the lens barrel, and the actuation force results in a relative motion of the window member with respect to the container.
