  • Method and composition for producing optical elements having a gradient structure
    Patent number: 8497051
    Abstract: A composition for producing optical elements having a gradient structure, particularly for holographic applications, is formed by a refractive index gradient. The composition is produced from one or more polymerizable and/or polycondensable monomers and at least one biological polymer. A potential difference is generated for the directed diffusion of the monomers by inducing a local polymerization or polycondensation. The result is the formation of a refractive index gradient.
    Type: Grant
    Filed: December 21, 2009
    Date of Patent: July 30, 2013
    Assignee: Leibniz-Institut fuer Neue Materialien Gemeinnuetzige GmbH
