INSPECTING OPHTHALMIC LENSES WITH MULTIPLE TYPES OF RADIATION

摘要

FIELD: physics.SUBSTANCE: invention relates to testing of ophthalmic lenses using radiation of different wavelength. According to said method, ophthalmic lenses placed in a container with packing solution at production line are exposed to radiation with different wavelength. Obtained images are compared to determine a defect.EFFECT: enabling determination of difference between defects of ophthalmic lenses and air bubbles in package.12 cl, 2 dwg
