METHOD, JIG, AND APPARATUS FOR MACHINING ROD LENSES

摘要

A rod lens manufacturing method having satisfactory machining accuracy and enabling mass production. In the method, lens assembly sheets, each holding at least a row of rod lenses, are prepared. The lens assembly sheets are then arranged on holding surfaces defined on a jig. The holding surfaces are inclined relative to a reference surface of the jig by a predetermined angle. Each of the lens assembly sheet is clamped so that optical axes of the rod lenses are inclined relative to a direction perpendicular to the reference surface by that predetermined angle. The lens assembly sheets are then ground and polished.
