Abstract
An optical mechanism is provided, including a housing, a holder, a lens received in the holder, a driving assembly, and a base connected to the housing. The holder is movably disposed in the housing, and the lens has a first surface exposed to a first side of the holder and facing a first inner sidewall surface of the housing. The driving assembly is disposed in the housing for driving the holder and the lens to move relative to the housing.
Claims20
An optical mechanism, comprising:
- an optical unit, featuring a light transmittable material allowing the light to pass through the optical unit and having a first surface and a second surface having plane structures that are mutually paralleled and constructing a first distance, wherein the first surface is not perpendicular to the optical axis,
- a base,
- a holder, connecting the optical unit and move relative to the base, wherein when viewed along the light axis, the holder has a polygonal profile, and the polygonal profile has a first side, a second side, a third side and a fourth side, wherein the third side and the fourth side are paralleled and constructed a second distance, wherein the first surface is parallel to the first side and the maximum second distance is longer than the maximum first distance,
- a driving assembly, driving the holder and the optical unit to move relative to the housing.
