Abstract: An optical element driving mechanism is provided. The optical element driving mechanism includes a fixed part, a movable part, and a first driving assembly. The movable part moves relative to the fixed part and holds an optical element with an optical axis. The first driving assembly drives the fixed part to move relative to the movable part. The first driving assembly includes a first coil and a first magnetic element. The first coil includes a winding axis, and the winding axis is not perpendicular to the optical axis. The first coil and the first magnetic element are arranged in a direction that is substantially perpendicular to the optical axis. When viewed along a direction that is parallel to the optical axis, the first coil does not overlap the first magnetic element.

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.

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.
