Abstract
An optical system is provided, including a base, a first lens driving module and a second lens driving module. The first lens driving module includes a first holder, a first magnet, and a first coil corresponding to the first magnet, wherein the first holder is used to hold a first optical element and has a first side. The second lens driving module includes a second holder, a second magnet, and a second coil corresponding to the second magnet, wherein the second holder is used to hold a second optical element and has a second side. The first side is adjacent and parallel to the second side, and no magnet is disposed on the first side or second side.
Claims20
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;
- at least one first magnet disposed in the first holder;
- a first coil adjacent to the first magnet, 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;
- at least one second magnet disposed in the second holder;
- a second coil adjacent to the second magnet, 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.
