  • Method for evaluating cosmetic defects of an optical device
    Patent number: 11169049
    Abstract: Disclosed is a method for evaluating cosmetic defects of an optical device, including: a first step of acquiring a first set of cosmetic defects of the optical device; a second acquiring step during which a second set of cosmetic defects of the optical device is acquired, the second set of cosmetic defects being different from the first set of cosmetics defects and including at least one cosmetic defect corresponding to a cosmetic defect of the first set of cosmetic defects; a determining step, during which a subset of the first set of cosmetic defects of the optical device is determined based on the comparison of the cosmetic defects of the second set of cosmetic defects and the cosmetic defects of the first set of cosmetic defects; and a determining step, during which a quality factor of the optical device is determined based on the subset of cosmetic defects.
