    摘要： An imaging lens assembly includes an optical element. The optical element includes a substrate, a nanostructure layer and an intermediate layer. The substrate is made of transparent material. A main component of the nanostructure layer is an aluminum oxide, and the nanostructure layer has a plurality of ridge-like protrusions which extend non-directionally. Each of the ridge-like protrusions is gradually tapered from a bottom of each of the ridge-like protrusions to a top of each of the ridge-like protrusions. The intermediate layer is disposed between the substrate and the nanostructure layer, wherein the intermediate layer includes a first film and a plurality of second films. A main component of the first film is a silicon dioxide, a main component of each of the second films is the silicon dioxide, and the second films are stacked with the first film.

    摘要： This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for lens design for full-duplex communication. In some aspects, a device may use a lens design that enables full-duplex operation through a lens by facilitating an avoidance or mitigation of self-interference during full-duplex operation. The lens may have a first, antenna-facing surface and a second, outward-facing surface and, to avoid or mitigate self-interference due to reflection off the lens, the first surface may have a first curvature associated with a relatively small radius. In such examples, the device may transmit wireless signaling from a transmitting element and a reflection off the lens may be dispersed or otherwise oriented away from a receiving element in accordance with a design of the first curvature. In some implementations, the lens may include an anti-reflective coating to further reduce reflection off the lens.

    摘要： An imaging lens assembly includes a plurality of optical lens elements, a single-piece-formed light blocking sheet and a lens barrel. The lens barrel has a circular light-passing hole corresponding to the plurality of optical lens elements and the single-piece-formed light blocking sheet. The single-piece-formed light blocking sheet has a central aperture corresponding to the lens barrel and the plurality of optical lens elements. A maximum aperture diameter is defined by the central aperture. The single-piece-formed light blocking sheet comprises a plurality of light blocking structures surrounding and disposed adjacent to the central aperture. A minimum inner radius of the central aperture is defined near the center of each of the light blocking structures.

    摘要： An imaging lens includes a light blocking sheet that includes an inner ring surface, a plurality of tapered light blocking structures, and a nanostructure layer. The inner ring surface surrounds an optical axis and defines a light passage opening. The tapered light blocking structures are disposed on the inner ring surface, and each tapered light blocking structure protrudes from the inner ring surface and tapers off towards the optical axis. The tapered light blocking structures are periodically arranged to surround the optical axis. The contour of each tapered light blocking structure has a curved part in a view along the optical axis. The curved part forms a curved surface on the inner ring surface. The nanostructure layer is disposed on the curved surface and has a plurality of ridge-like protrusions that extend non-directionally, and the average structure height of the nanostructure layer ranges from 98 nanometers to 350 nanometers.

    摘要： A camera module includes an imaging lens assembly and an image sensor, wherein the image sensor is located on an image side of the imaging lens assembly. The imaging lens assembly has an optical axis and includes a plastic lens barrel and a plurality of plastic lens elements, wherein the plastic lens elements are disposed in the plastic lens barrel. The plastic lens barrel includes an object-side outer surface, a lens barrel minimum opening, an object-side outer inclined surface and a reversing inclined surface. The object-side outer surface is a surface of the plastic lens barrel facing towards an object side being closest to the object side and is annular. The reversing inclined surface expands from the lens barrel minimum opening to the image side, wherein a connecting position of the reversing inclined surface and the object-side outer inclined surface forms the lens barrel minimum opening.

    摘要： An annular optical element having an optical axis includes an outer diameter surface, an inner annular surface, an object-side surface and an image-side surface. The object-side surface includes an annular reflecting surface, an annular auxiliary surface and a connecting surface. The annular reflecting surface is inclined with the optical axis. The annular auxiliary surface is closer to the optical axis than the annular reflecting surface is to the optical axis. The connecting surface is for connecting to an optical element, wherein the connecting surface is closer to the optical axis than the annular auxiliary surface is to the optical axis. The image-side surface is located opposite to the object-side surface and includes an annular optical surface. A V-shaped groove is formed by the annular auxiliary surface and the annular reflecting surface of the object-side surface.
