  • Patent number: 11714212
    Abstract: Optical coatings for curved or non-planar substrates are disclosed. Optical coatings may include AR (antireflection) coatings or absorbing (“black” optical) coatings. The optical coatings may include a nanostructure layer formed on top of a stack of one or more materials. Both the nanostructure layer and the stack may be deposited on a curved or non-planar substrate using plasma-enhanced atomic layer deposition (PEALD) to provide conformal coating of the substrate. The nanostructure layer may include a mixture of aluminum hydroxide and aluminum oxide hydroxide that is formed by placing a PEALD-deposited aluminum oxide layer in heated deionized water for a predetermined time period. The materials in the stack may be alternated to provide tuning of the optical properties in the optical coating.

  • Patent number: 11409078
    Abstract: Various embodiments disclosed herein include camera equipment having a refractive index layer that causes internal reflection close to an image sensor of the camera. In some examples, internal reflection may occur at a boundary formed with the refractive index layer and located between an image sensor and an upper surface of a lens of the camera. The boundary may be formed between the refractive index layer and another material located between the refractive index layer and the image sensor, wherein the refractive index layer has a lower index of refraction than other material between the refractive index layer and the image sensor. The boundary formed with the refractive index layer may cause light to be reflected back toward the image sensor to improve image quality of images captured by the image sensor.
