  • Producing microstructured spectacle lenses by means of transfer layer
    Patent number: 10274749
    Abstract: A method for producing a spectacle lens having in particular a diffractive microstructure on at least one lens surface. To this end, a thin structural support layer is initially made available, which on a surface has a microstructure. A lens main body is then cast to the microstructure of the structural support layer.
    Type: Grant
    Filed: November 19, 2013
    Date of Patent: April 30, 2019
    Assignee: Rodenstock GmbH
    Inventors: Stephan Trumm, Karl Huber, Ferdinand Schreder, Erich Koell, Herbert Schuster, Reiner Beck, Herbert Zinner, Werner Mueller
  • CREATION OF MICROSTRUCTURED SPECTACLE LENSES IN PRESCRIPTION LENS PRODUCTION
    Publication number: 20160008942
    Abstract: A method for providing spectacle lenses that have a microstructure on at least one side. A procedure is described, in which the structure is introduced into a face of the lens after the processing of the face of the lens. Processing steps used to achieve the optical quality of the corresponding surface can be omitted. The back face of a spectacle lens may be microstructured by CNC-controlled turning after a first shaping processing, wherein the polishing step is omitted.
