    Abstract: A lens driving mechanism is provided for moving a lens unit along a light axis, including a frame, a base, a lens holder, and a driving assembly. The frame has plastic material and forms an opening. The base is in contact with and fixed to the frame, wherein a space is formed between the base and the frame. The lens holder is movably disposed in the space for holding the lens unit, wherein an external light enters the space through the opening to the lens unit. The driving assembly is disposed in the space and is connected to the lens holder and the frame, to impel the lens unit to move along the light axis.

    Abstract: An optical system includes a fixed module, a movable module and a driving assembly. The movable module moves relative to the fixed module, and the movable module includes a lens unit which includes a first lens, a second lens, a first side wall and a second side wall. The first side wall has a first surface, which directly contacts the second lens, and the second side wall directly contacts the first lens. A portion of the driving assembly is directly disposed on the lens unit, configured to drive the lens unit to move along an optical axis of the first lens. The first side wall further has a second surface opposite to the first surface, and the second surface directly contacts the portion of the driving assembly. The thickness of the first side wall is different from the thickness of the second side wall.

    Abstract: An optical element driving module is provided, including a movable portion, a fixed portion, and a driving assembly. The movable portion is used for connecting an optical element. The fixed portion is movably connected to the movable portion, wherein the fixed portion includes a base and a casing. The casing is arranged with the base along a main axis, the casing includes a top wall and a side wall extended from edges of the top wall along the main axis, and the top wall includes a first surface facing the movable portion, a second surface and a third surface facing away from the first surface. The driving assembly is used for moving the movable portion relative to the fixed portion, a minimum distance between the first surface and the second surface is different from a minimum distance between the second surface and the third surface.
