  • Method of producing an optical device and a corresponding system
    Patent number: 11548215
    Abstract: A method of producing an optical device from a volume of a curable composition, includes the following steps: —polymerizing a first portion of the volume by irradiating an external surface of the volume with a light irradiation, thereby increasing a transmittance of the first portion for the light irradiation; —polymerizing a second portion of the volume by irradiating the second portion with the light irradiation through the external surface and the polymerized first portion, wherein the light irradiation has a light intensity varying over the external surface between a first light intensity and a second light intensity distinct from the second light intensity. A corresponding system is also described.
    Type: Grant
    Filed: June 30, 2017
    Date of Patent: January 10, 2023
    Assignees: NIKON CORPORATION, ESSILOR INTERNATIONAL, CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE, UNIVERSITE DE HAUTE-ALSACE (UHA)
    Inventors: Olivier Soppera, Manuel Theodet
  • Method for making a self-aligned optical guide between an optical source and an optical fiber, and related kit
    Patent number: 11054579
    Abstract: A method includes placing a fluid guide forming composition in contact with the optical source and with the optical fiber, injecting a first light in the guide forming composition from the optical source and/or from the optical fiber, to harden a central region of the optical guide, illuminating the guide forming composition with the second light to harden a peripheral region of the optical guide by photopolymerization initiated by the second photoinitiator system. The difference between the first peak wavelength and the second peak wavelength being more than 100 nm.
