Abstract
A method and apparatus are provided for batch, continuous, or semi-continuous coating of optical lenses. The method and apparatus use a plurality of carriages which are reciprocally moved in the apparatus to transfer jigs from a jig filled carriage to a lens loading arm and to load the jigs with lenses and then to transfer the jigs now containing uncoated lenses to a leading empty carriage. Using such a reciprocating motion, a leading empty carriage is now filled with jigs containing uncoated lenses and the uncoated lenses in the carriage may then be coated by dipping the carriage in a coating tank. After coating, the coated lenses are removed from the system. A similar reciprocating motion is used in the coated lens unloading section.
