The urging member is held by the second barrel member inside the second barrel member, and is in contact with the outer surface of the third barrel member.

An optical assembly for an autofocus imaging system for capturing at least one image of an object appearing in an imaging field of view (FOV) is provided. The optical assembly includes a front aperture along an optical axis and a front lens group along the optical axis that receives light from the object of interest. The position of the front lens group is adjustable to change a focal distance of the optical assembly. The optical assembly further includes an actuator physically coupled to the front lens group that adjusts the position of the front lens. A rear lens group is disposed along the optical axis to receive the light from the front lens group, and an imaging sensor is disposed at a back focal distance of the rear lens group, to detect the light.

A diffusion apparatus includes a diffuser, a substrate to which the diffuser is fixed, and a first lens that has a curved surface and a flat surface located on the side opposite the curved surface and is so fixed to the substrate as to face the diffuser. The substrate includes a first recess having a first bottom surface and a first side surface that rises from the first bottom surface and a second recess having a second bottom surface connected to the first side surface and a second side surface that rises from the second bottom surface. The first lens is so disposed in the second recess that the flat surface is in contact with the second bottom surface. The diffuser is fixed to the first bottom surface.

The present disclosure provides a camera module and an optical lens thereof, an optical lens element and a manufacturing method therefor, and a method for assembling a large wide-angle camera module, wherein the camera module comprises a lens and a photosensitive assembly. The lens comprises a lens barrel, at least one first lens element unit and at least one second lens element unit, and is further provided with at least one notch, wherein the first lens element unit and the second lens element unit are disposed in the lens barrel, and the first lens element unit is configured as a non-rotating body, and wherein the notch is provided in the lens barrel, or the notch is formed in the first lens element unit, or the notch is formed in the second lens element unit, and the first lens element unit is marked by means of the notch.

Various embodiments include a camera having an actuator arrangement with a low-profile actuator arrangement. For example, the camera may include a voice coil motor (VCM) actuator to move a lens group and/or an image sensor of the camera. According to some embodiments, the VCM actuator may include one or more magnet-coil groups located beside an image sensor package of the camera. In some embodiments, a magnet-coil group may be located between the image sensor package and a side wall of the camera. Additionally, or alternatively, the magnet-coil group may at least partially extend (e.g., in a direction parallel to an optical axis defined by the lens group) past an upper surface of the image sensor and a bottom of the camera in some embodiments.

A lens unit and a camera module in which the electrical wiring extending from the electrically functional component in the lens barrel can be guided to the image side without interfering with an assembly operation, without the need of ensuring a wiring space in the lens barrel, and without forming an elongated through hole in the lens barrel. The lens barrel includes: i) a first through hole extending in the longitudinal direction inside the side wall to guide the electric wiring from the component to the image side end of the flange; ii) a second through hole extending radially on the side wall so the first through hole can communicate with the outside of the barrel; iii) an accommodation groove on the outer peripheral surface of the side wall to communicate with the second through hole, in order to accommodate the wiring and guide the wiring to the image side.

An impact- and vibration-proof lens module includes a fixing assembly, a circuit board, a lens assembly, and a buffering pad. The fixing assembly defines a chamber, and the circuit board is partially disposed in the chamber. The lens assembly is disposed on the circuit board, and the lens assembly is also partially disposed in the chamber. The buffering pad made of thermally conductive silicon is disposed in the chamber and is disposed between the circuit board and the fixing assembly. In the event of being dropped or suffering vibration, the buffering pad disperses and absorbs stress on the fixing assembly to prevent breakage.

A lens unit includes a plurality of lenses arranged in an optical axis direction, a lens barrel, and a retainer. The lens barrel has an opening larger than outer diameters of the plurality of lenses and contains the plurality of lenses. The retainer holds the plurality of lenses by contacting, from a side adjacent to the opening in the lens barrel, one of the plurality of lenses that is closest to the opening. Each of the plurality of lenses has an object-side surface and an image-side surface which each include a flat portion that extends radially inward from an outer edge of the lens and that is perpendicular to the optical axis direction of the lens. Each of the plurality of lenses is held in planar contact with a holder at the flat portion. The retainer holds the plurality of lenses by biasing the plurality of lenses in the optical axis direction.

A high-power laser processing head has precisely centered stationary lenses. The assembly of the lenses in the head can reduce contamination. The lens is affixed (soldered) in a ring-shaped highly precise mount, which ensures a high thermal conductivity of the joining interface. The mount and lens can be cleaned as a unit and inserted in a precisely manufactured receptacle of a housing module. A seal can provide sealing between an inner surface in the receptacles and a base surfaces of the mount. The modules has a groove around the diameter of the receptacle to catch any particles generated when inserting the lens mounts into the receptacle. The assembly is clamped into place by the next housing module. The lens is directly cooled by the module's body to mitigate contamination on the lens surface. During repairs, both lens and mount can be exchanged as a unit.
