INSPECTING OPHTHALMIC LENSES WITH MULTIPLE TYPES OF RADIATION Russian patent published in 2016 - IPC G01N21/896 G01M11/02 G02C7/04

Abstract RU 2586391 C2

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.
