Abstract: The invention relates to an arrangement for a tunable lens, which comprises a deformable lens shaping element (1) with a central axis (2) and a radial axis (5) and with a perimetrical edge (3) that extends about the central axis (2) and wherein the perimetrical edge (3) 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 (13), which is mechanically coupled to the lens shaping element (1) by a bearing, wherein the bearing limits an axial translational degree of freedom (7), such that an axial force is transmittable between the lens shaping element (1) and the adjustment element (13) parallel to the central axis (2) and wherein the bearing provides a radial rotational degree of freedom (12) for a relative rotation between the lens shaping element (1) and the adjustment element (13) about the radial axis (5).

Abstract: The invention relates to a tiltable mirror device (1) comprising the components: a tiltable portion (2) comprising a substrate (2.1) having a reflective layer (2.2) for reflecting electromagnetic waves, a fixed portion (3) relative to which the tiltable portion (2) is movable, a bearing assembly (4) mechanically connecting the fixed portion (3) and the tiltable portion (2), wherein the bearing assembly (4) is arranged to render the tiltable portion (2) tiltable around at least one axis of rotation (100) with respect to the fixed portion (3), an actuator assembly, wherein the actuator assembly comprises two components, namely a coil portion (6) comprising one or more coils (6.1, 6.2) each comprising an electric conductor (6.
