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;
- 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;
- 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;
- wherein the first side is adjacent to the second side, and no magnet is disposed on the first side or the second side.
