  • Anodized part having low reflectance of visible and near-infrared light
    Patent number: 11614778
    Abstract: This application relates to an enclosure for a portable electronic device. The enclosure includes a metal substrate, and an anodized layer overlaying the metal substrate and including pores having a near-infrared (NIR) light-absorbing material therein, where an average specular reflectance of NIR light that is incident upon an external surface of the anodized layer is less than 3%.
    Type: Grant

    Date of Patent: March 28, 2023
    Assignee: APPLE INC.
    Inventors: James A. Curran, Alan Kleiman-Shwarsctein, Leon J. Garcia, Jr.
  • Single Element Light Folding Prism
    Publication number: 20220163706
    Abstract: An optical system for a camera may include a lens group having a one or more lenses, a prism, and an image sensor. The prism may be a single element light folding prism positioned between the lenses and the image sensor along the optical transmitting path of the light. The prism may be constructed from a single, monolithic piece of stock material and may include at least four surfaces, which may fold the light within the prism at least four times to guide the light from the one or more lenses passing through the prism to the image sensor. The prism may also include one or more aperture masks inside the prism to reduce flare.
