1. An optical system, comprising a first optical mechanism, the first optical mechanism including:
a first movable part, including a first optical element;
a fixed assembly, wherein the first movable part is movable relative to the fixed assembly;
a first driving assembly, configured to drive the first movable part to move relative to the fixed assembly; and
a guiding assembly, configured to guide the first movable part to move relative to the fixed assembly, wherein a friction force is generated by the first movable part and the guiding assembly, and the first movable part is temporarily positioned on the fixed assembly through the friction force;
wherein the fixed assembly includes:
a first opening, configured to allow a first light beam to pass through to enter a second optical mechanism; and
a second opening, configured to allow a second light beam to pass through to enter a third optical mechanism;
wherein the first light beam is parallel to the second light beam;
the second optical mechanism includes a camera module configured to capture an image;
the third optical mechanism includes a depth-sensing module configured to measure distance;
when viewed along a first axis, the first opening and the second opening are arranged along a second axis;
the first axis is parallel to the first light beam;
the second axis is perpendicular to the first axis;
wherein when viewed along the first axis, the first driving assembly and the first opening are arranged along the second axis;
when viewed along the second axis, the first opening overlaps at least a part of the second opening;
when viewed along the first axis, the fixed assembly has a long strip-shaped structure extending along the second axis;
when viewed along the first axis, the first opening is located on a first end portion of the fixed assembly;
wherein the first optical mechanism further includes a supporting assembly configured to affix the fixed assembly to a base body of the optical system;
when viewed along the first axis, the first opening is located between the supporting assembly and the first driving assembly;
the supporting assembly and the fixed assembly form a first accommodation space;
at least a part of the second optical mechanism is located in the first accommodation space;
the supporting assembly includes a first supporting element, and the first supporting element has a columnar structure, a flat plate-shaped structure, or a U-shaped plate structure;
the first supporting element includes a shock-absorbing material.
