Abstract: Described herein is an arrangement for a tunable lens, which comprises a deformable lens shaping element with a central axis and a radial axis and with a perimetrical edge that extends about the central axis and wherein the perimetrical edge is designed to interact and mechanically deform a membrane of the tunable lens in order to change at least one optical property of the tunable lens. The arrangement further comprises a moveable adjustment element, which is mechanically coupled to the lens shaping element by a bearing, wherein the bearing limits an axial translational degree of freedom, such that an axial force is transmittable between the lens shaping element and the adjustment element parallel to the central axis and wherein the bearing provides a radial rotational degree of freedom for a relative rotation between the lens shaping element and the adjustment element about the radial axis.
