The lens barrel is embedded in the accommodating cavity of the lens holder and is in threaded connection with the lens holder. The fixed pressing plate is fixed to one side of the lens barrel away from the lens holder and is capable of moving axially relative to the lens holder.

A LiDAR system may include an optical component module including a housing including a plurality of slots and a plurality of posts. A first spring may be coupled to a first post at a first radial orientation so that the first spring extends into a first slot of the plurality of slots. A second identical spring may be coupled to a second post in a second radial orientation, different than the first radial orientation, so that the second spring extends into a second slot of the plurality of slots. A first optical component may be positioned in the first slot so that the first spring exerts a first clamping force retaining the first optical component within the first slot, and a second optical component may be positioned in the second slot so that the second spring exerts a second clamping force retaining the second optical component within the second slot.

An image pickup apparatus which is capable of stably detecting rotating operations of a rotary ring provided on an outer periphery of a lens barrel or the like. A holding member is provided on an inner periphery of the rotary ring to hold the rotary ring. A rotation detecting member detects a rotation direction and a rotation amount of the rotary ring when the rotary ring has been rotated. An urging member urges the rotary ring against the holding member in an urging direction perpendicular to a rotational axis of the rotary ring. A detecting direction of the rotation detecting member and the urging direction of the urging member are parallel to each other.

A focusing device includes a fixing base, a screw rod, a focusing gear, a height adjusting ring, and a focusing ring. A first through hole is defined in the fixing base, the screw rod with a first thread is movably mounted on the fixing base. The focusing gear is also mounted on the fixing base and defines a third through hole corresponding to the first through hole. An outer wall of the focusing gear has an engaging portion meshing with the first thread. The focusing ring is movably received in the third through hole and located on a side of the height adjusting ring away from the fixing base. The height adjusting ring can adjust a distance between the focusing ring and a lens module to avoid distortion of an optical lens in any circumstances during focusing.

An imaging lens module includes a plastic lens barrel, a first optical element assembly and a second optical element assembly, wherein both of the first optical element assembly and the second optical element assembly are disposed in the plastic lens barrel. The plastic lens barrel includes a first inner annular surface and a second inner annular surface. The first inner annular surface forms a first receiving space. The second inner annular surface forms a second receiving space. The first optical element assembly is disposed in the first receiving space and includes a plurality of optical lens elements and a first retainer. The second optical element assembly is disposed in the second receiving space and includes a first light blocking sheet and a second retainer.

A lens (10) and a camera module (100) and a manufacturing method thereof, wherein the lens (10) comprises an edge-cut lens sheet (114), wherein the edge-cut lens sheet (14) includes at least one chord edge (1141) and at least one circular edge (1142), wherein the chord edge (1141) and the circular edge (1142) are adjacently connected to each other, and wherein the chord edge (1141) and the circular edge (1142) have different curvatures, so that the lens sheet (114) becomes narrow and the width of the lens (10) become narrow, to form an ultra-narrow camera module (100).

The disclosure relates to an optical system and to a method for operating an optical system, wherein the optical system includes at least one carrier having at least one optical element, a movement bearing element for supporting the carrier during a movement, at least one first bearing element and at least one further bearing element for statically supporting the carrier, wherein the carrier includes corresponding bearing elements for providing static support, wherein the optical system includes a first and a further end stop element, wherein the carrier is supported movably between the end stop elements, wherein the first end stop element has or forms the first bearing element for providing static support and the further end stop element has or forms the further bearing element for providing static support, wherein the bearing elements define the stop poses of the carrier with repetition accuracy.

A camera assembly for inclusion in a camera is described. The camera assembly includes a lens barrel and a retaining mechanism that is configured to restrict movement of the lens barrel relative to the retaining mechanism. The retaining mechanism is configured to be attached to a mounting surface of a camera enclosure, such that position of the camera assembly remains fixed relative to the camera enclosure.
