  • Method for shaping an optical component in order to produce an aspherical surface
    Patent number: 9937674
    Abstract: A method for shaping an optical component so that it has an aspherical optical surface. In the method: the optical component is heated and mechanical stresses are applied thereto; heating and applying the mechanical stresses are stopped; an optical surface of the component is polished into a planar or spherical shape; and viscous elastic deformation of the optical component is relaxed. The method for example has applications in manufacturing aspheric mirrors having great dimensions.
    Type: Grant

    Date of Patent: April 10, 2018
    Assignee: Commissariat à l'énergie atomique et aux énergies alternatives
    Inventors: Thomas Lanternier, Stephane Bouillet
