    摘要： An optical system is provided, including a light source, a fixed portion, an optical assembly, and a driving assembly. The light source is used for generating light. The optical assembly has an equivalent focal length to the light. The optical assembly includes a first optical element and a second optical element. The driving assembly is used for driving the second optical element to move relative to the first optical element. When the second optical element is at a first position, the equivalent focal length is a first focal length. When the second optical element is at a second position, the equivalent focal length is a second focal length. The first focal length and the second focal length are different.

    摘要： An optical element driving mechanism includes a movable portion, a fixed portion, a driving assembly, a guiding assembly, and a metallic member. The movable portion is configured to connect an optical element. The optical element is configured to correspond to light reflected by a reflection element, and the reflection element is configured to change a traveling direction of the light from an incident direction to a first direction. The fixed portion includes a base, and the movable portion is movable relative to the fixed portion. The driving assembly is configured to drive the movable portion to move relative to the fixed portion. The guiding assembly includes a plurality of guiding elements. The metallic member is disposed in the base. When viewed from the incident direction, the metallic member is at least partially located between the guiding elements.

    摘要： An optical element driving mechanism for corresponding to an optical module, the optical element driving mechanism including a fixed portion, a movable portion, and a first driving assembly. The fixed portion has an aperture. The movable portion is for connecting to an optical element and is movable relative to the fixed portion. The first driving assembly is for driving the movable portion to move relative to the fixed portion. The fixed portion has an elongated structure, and the fixed portion further comprises a first end. The fixed portion further comprising a second end, wherein the first end and the second end are arranged along a first direction. A shortest distance between the optical sensing element and the first end is shorter than a shortest distance between the optical sensing element and the second end.
