Abstract

An optical system is provided and includes a first optical element driving mechanism, which includes a first fixed assembly, a first movable assembly, and a first driving assembly. The first movable assembly is configured to be connected to at least two first optical element, and the first movable assembly is movable relative to the first fixed assembly. The first movable assembly includes a first movable element. The first drive assembly is configured to drive the first movable assembly to move relative to the first fixed assembly. The first fixed assembly and the first movable assembly are arranged along a main axis, the first driving assembly is configured to drive the first movable element to move around the main axis, and a portion of the first driving assembly is disposed on the first movable element.
