  • Multi-wavelength wavefront system and method for measuring diffractive lenses
    Patent number: 10895517
    Abstract: A multi-wavelength wavefront system and method for measuring diffractive lenses. A system may include one or more light sources configured to emit a plurality of wavelengths of light for diffraction by a diffractive lens. A light sensor may be configured to receive the light that is diffracted by the diffractive intraocular lens. A processor may be configured to determine one or more of the plurality of wavelengths that have a peak diffraction efficiency for the diffractive intraocular lens based on the light received by the light sensor.
    Type: Grant
    Filed: February 8, 2019
    Date of Patent: January 19, 2021
    Assignee: AMO Groningen B.V.
