1. An optical system, comprising:
a first optical element driving mechanism, comprising:
a first fixed assembly;
a first movable assembly, configured to be connected to a first optical element, wherein the first movable assembly is movable relative to the first fixed assembly, and the first movable assembly comprises a first movable element and a second movable element; and
a first driving assembly, configured to drive the first movable assembly to move relative to the first fixed assembly;
wherein the first fixed assembly and the first movable assembly are arranged along a main axis, and the first driving assembly is configured to drive the second movable element to move along a first axis, thereby driving the first movable element to move around the main axis;
wherein the optical system further comprises a second optical element driving mechanism;
the first optical element driving mechanism is disposed on the second optical element driving mechanism;
the second optical element driving mechanism comprises a second driving assembly;
the second optical element driving mechanism further comprises a circuit assembly electrically connected to the first driving assembly and the second driving assembly;
the circuit assembly comprises a substrate, a sharing element, a first circuit element and a second circuit element;
the sharing element, the first circuit element and the second circuit element each has a long strip-shaped structure;
the sharing element bends from the substrate to extend along a second axis;
the second axis is perpendicular to the first axis;
the second axis is parallel to the main axis;
when viewed along the first axis, the first circuit element straightly extends in a first direction from the sharing element without bending;
when viewed along the first axis, the second circuit element straightly extends in a second direction from the sharing element without bending;
the first direction is the opposite of the second direction.
