    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 system is provided and includes a fixed assembly, a movable element, a movable assembly, and a driving module. The fixed assembly defines a main axis, and the fixed assembly has a casing on which a casing opening is formed, corresponding to the main axis. The movable element is movable relative to the fixed assembly and is connected to a first optical element. The movable assembly is connected to the movable element. The driving module is configured to drive the movable assembly so as to drive the movable element to move relative to the fixed assembly. The first optical element has a first section and a second section. When viewed along the main axis, the size of the first section is larger than the size of the casing opening, and the size of the second section is smaller than the size of the casing opening.
