  • Interferometer having a reference fluid tank with a prism and a motion matching window for characterizing a contact lens
    Patent number: 10416039
    Abstract: The system and methods are made to apply interferometry to ophthalmic applications. The system makes use of a low-coherence interferometer to obtain a plurality of measurements of a contacts lens. The system and methods characterizes the surface profile of both surfaces of a contact lens, a thickness profiles, and combines these measurements with an index information to reconstruct a complete model of the contact lens.
    Type: Grant
    Filed: March 28, 2019
    Date of Patent: September 17, 2019
    Assignee: Johnson & Johnson Vision Care, Inc.
    Inventors: John E. Greivenkamp, Jr., James William Haywood, Kyle C. Heideman, Russell T. Spaulding, Gregory Allen Williby
