Optical system

An optical system, comprising:

• a first optical mechanism, comprising:
• a movable part;
• a fixed assembly, wherein the movable part is movable relative to the fixed assembly;
• and
• a driving assembly, configured to drive the movable part to move relative to the fixed assembly;
• a second optical mechanism;
• and
• a third optical mechanism;
• wherein when viewed along a first axis, a base of the fixed assembly is disposed between the second optical mechanism and the third optical mechanism;
• the optical system further comprises a base plate, and the base of the first optical mechanism, the second optical mechanism and the third optical mechanism are fixedly disposed on the base plate and located on a same plane;
• the fixed assembly further comprises an outer frame fixedly connected to the base;
• when viewed along the first axis, the outer frame has a long strip-shaped structure extending along a second axis;
• the outer frame has a base portion, a first bending portion and a second bending portion;
• when viewed along a third axis, there is a gap between the first bending portion and the base plate;
• the third axis is perpendicular to the first axis and the second axis;
• and
• when viewed along the third axis, there is another gap between the second bending portion and the base plate.
