Optical system

An optical system with a first direction and a second direction perpendicular to each other, comprising:

• a fixed part;
• a first optical element driving module, comprising:
• a first holder, having a first receiving space for holding a first optical element with a first optical axis;
• a first driving assembly, driving the first holder to move relative to the fixed part, comprising:
• a first magnet;
• and
• a first coil, corresponding to the first magnet;
• a second optical element driving module, comprising:
• a second holder, having a second receiving space for holding a second optical element with a second optical axis;
• a second driving assembly, driving the second holder to move relative to the fixed part;
• wherein in a direction that is perpendicular to the first optical axis, a maximum size of the first receiving space is different from a maximum size of the second receiving space;
• wherein a central line is defined between the first optical element driving module and the second optical element driving module;
• wherein the first optical element driving module comprises a first side, the second optical element driving module comprises a second side, the first side is adjacent to the second side, and the central line is located between the first side and the second side, wherein no first magnet is disposed at the first side.

An optical system with a first direction and a second direction perpendicular to each other, comprising:

• a fixed pan;
• a first optical element driving module, comprising:
• a first holder, having a first receiving space for holding a first optical element with a first optical axis, wherein the first optical axis, the first direction, and the second direction are perpendicular to each other;
• a first driving assembly driving the first holder to move relative to the fixed part, comprising:
• two first magnets, arranged along the first direction, wherein the two first magnets have rectangular structures and extend along the second direction;
• and
• a first coil, corresponding to the first magnet;
• a second optical element driving module, comprising:
• a second holder, having a second receiving space for holding a second optical element with a second optical axis;
• a second driving assembly, driving the second holder to move relative to the fixed part;
• wherein in a direction that is perpendicular to the first optical axis, a size of the first receiving space is larger than a size of the second receiving space;
• wherein no magnet is disposed at opposite sides of the first optical element driving module along the second direction.
