  • OPTICAL LENS DEVICE HAVING A POLARIZATION MINIATURE STRUCTURE AND METHOD THEREOF
    Publication number: 20230071479
    Abstract: An optical lens device includes an optical substrate layer, an optical thin film, an optical polarization layer and a miniature surface structure. The optical substrate layer has a first surface and a second surface and rays of light passes through the optical substrate layer. The optical polarization layer is provided on a surface of the optical thin film. The miniature surface structure is physically processed to form the optical polarization layer and provides a characteristic of optical polarization in the optical polarization layer. The miniature surface structure of the optical thin film provides an optical polarization effect to the rays of light while passing through it.

  • OPTICAL LENS DEVICE HAVING AN ETCHED POLARIZATION MINIATURE STRUCTURE AND METHOD THEREOF
    Publication number: 20220390653
    Abstract: An optical lens device includes an optical substrate layer, an etched miniature-structure polarization layer and an etched miniature surface structure. The optical substrate layer is provided with a first surface and a second surface and a ray of light passes through the optical substrate layer. The etched miniature-structure polarization layer is provided on the first surface or the second surface of the optical substrate layer. The etched miniature surface structure is etched to form the miniature-structure etched polarization layer and provides a characteristic of optical polarization in the etched miniature-structure polarization layer. The etched miniature surface structure of the etched miniature-structure polarization layer provides an effect of optical polarization to the ray of light while passing through it.
