An optical system, comprising:
- a base;
- a first driving module, comprising:
- a first holder configured to receive a first optical element and having a first side and a third side, when viewed in an optical axis of the first optical element, the optical system is polygonal;
- a first coil disposed on the first holder;
- at least one first magnet adjacent to the first coil, wherein a magnetic force is generated between the first coil and the first magnet to move the first holder and the first optical element relative to the base, the at least one first magnet is strip-shaped, extending along the third side, and disposed at the third side;
- and
- a second driving module, comprising:
- a second holder configured to receive a second optical element and having a second side;
- a second coil disposed on the second holder;
- and
- at least one second magnet adjacent to the second coil, wherein a magnetic force is generated between the second coil and the second magnet to move the second holder and the second optical element relative to the base, when viewed along the optical axis, the at least one second magnet is disposed at a corner of the optical system;
- wherein the first side is adjacent to the second side, and no magnet is disposed on the first side or the second side.
