    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.

    IPC: G02B7/09

    Abstract: An optical element driving mechanism is provided, including a base, a holder movably coupled to the base for holding an optical element, a casing, a frame, a driving assembly, and an adhering member. The casing has a top wall and a plurality of side walls extending from the edge of the top wall along an optical axis of the optical element, and the top wall is closer to a light-incident end than the base. The frame is disposed on the top wall and has a frame protrusion extending toward the base. The driving assembly is configured to drive the holder to move relative to the base, and an accommodating space is formed between the base, the frame and the casing. The adhering member is disposed in the accommodating space and configured to directly adhere to the base, the frame, the casing, and the driving assembly.

    Abstract: A driving mechanism is provided for moving an optical element, including a fixed module, a movable module holding the optical element, a driving assembly for driving the movable module to move relative to the fixed module, a position-sensing element, and a 3D circuit. The fixed module has a base, and the position-sensing element is disposed on the base to detect the movement of the movable module relative to the fixed module. The 3D circuit is embedded in the base and electrically connected to the position-sensing element.
