1. An optical system, comprising:
an optical module with a main axis, comprising;
a fixed portion;
a movable portion connected to an optical element and movable relative to the fixed portion;
a driving mechanism driving the movable portion to move relative to the fixed portion;
a supporting assembly connected to the movable portion and the fixed portion; and
a circuit assembly electrically connected to a circuit located outside the optical module;
wherein when viewed along a direction that is parallel with the main axis, the fixed portion is a polygonal structure with a first side, a second side, a third side, and a fourth side;
wherein the first side is parallel with the third side, the second side is parallel with the fourth side, and the first side is not parallel with the second side;
wherein the fixed portion comprises an outer frame and a frame connected to the outer frame, a first accommodating space is formed to accommodate the movable portion and the frame, and the outer frame comprises:
a top wall having a plate-like structure and not parallel with the main axis;
a first side wall extending from a first edge of the top wall and not parallel with the top wall;
a second side wall extending from a second edge of the top wall and not parallel with the top wall;
a third side wall extending from a third edge of the top wall and not parallel with the top wall; and
a fourth side wall extending from a fourth edge of the top wall and not parallel with the top wall, wherein the fourth side wall has an opening corresponding to a light;
wherein the movable portion comprises:
a pedestal connected to the optical element and having a plate-like structure; and
a holder fixedly disposed on the pedestal;
wherein the circuit assembly comprises:
a first circuit fixedly disposed on the pedestal and integrally formed with the pedestal;
a second circuit fixedly disposed on the holder and at least partially embedded in the holder;
a third circuit fixedly disposed on the frame and at least partially buried in the frame; and
an external circuit connected to the circuit outside the optical module.
