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.
