Claim 17:
18. Optical device (1), comprising:
an optical element (21) configured to interact with a light beam (L) impinging on the optical element (21),
a support frame (3) configured to support the optical element (21),
a spring structure (900) connected to the support frame (3), wherein the spring structure (900) comprises a frame (909) to which the optical element (21) is connected, wherein the frame (909) is moveable with respect to the support frame (3), and wherein the spring structure (900) comprises a first holding member (902) that is connected via a first spring element (901) to the frame (909), and
an actuator (5) configured to move the frame (909) with respect to the support frame (3) by means of a Lorentz force,, wherein the actuator (5) comprises a first coil (60), a second coil (61), a third coil (62) and a fourth coil (63), wherein said coils (60, 61, 62, 63) are integrated into the support frame (3), and wherein the actuator (5) comprises a first magnet (70) facing the first coil (60), a second magnet (71) facing the second coil (61), a third magnet (72) facing the third coil (62), and a fourth magnet (73) facing the fourth coil (63), wherein the magnets (70, 71, 72, 73) are connected to the frame (909).
