Abstract
A chucking method and apparatus for processing a lens blank in a manner requiring only a single mounting of the blank to an associated lens block. The lens block is mounted to the convex lens blank surface by a hot melt type of adhesive so as to extend outwardly thereof substantially coaxial with the lens blank frame center axis. The lens blank and lens block are releasably mounted in a chuck assembly associated with lens surface generating apparatus such that a desired optical center axis in the lens blank and the tailstock of the generating apparatus are coaxial. The chuck includes means for selectively rotating and/or canting the lens blank relative to the tailstock to accommodate desired axis and prism settings as prescribed for the finished lens. Following generation of the desired optical characteristics in the lens blank, additional operations are performed thereon for producing a finished optical lens while the lens block remains affixed thereto. After these additional operations are completed, the lens block is removed from mounted association with the finished optical lens.
