Abstract: An optical system is provided, including a first optical member driving mechanism, a second optical member driving mechanism, and a first fixing component. The first optical member driving mechanism includes a first fixed portion, a first movable portion, a plurality of elastic members, and a first driving module. Each of the elastic members is elastically connected to the first fixed portion and the first movable portion. The second optical member driving mechanism includes a second fixed portion, a second movable portion, and a second driving module. The second movable portion is movably connected to the second fixed portion. The second driving module can drive the second movable portion to rotate relative to the second fixed portion. The first fixing component affixes the first optical member driving mechanism to the second optical member driving mechanism.

Abstract: The present invention relates to an optical element driving mechanism, including a base, a holder, a frame and a light intensity adjusting assembly. The holder is movably connected to the base and carries the optical element, wherein the optical element has an opening and an optical axis so that light passes through the opening to the optical element. The frame is connected to the holder and the base. The light intensity adjusting assembly is disposed on the frame. The light intensity adjusting assembly includes a first shutter, a second shutter and a shutter driving member. The second shutter is disposed between the first shutter and the frame. The shutter driving member is disposed between the second shutter and the frame to drive the first shutter and the second shutter.
