ABSTRACT:
A method of forming precision glass molds suitable for molding glass optical elements or lenses is disclosed. The glass molds define first and second opposed optical molding surfaces. Each master is formed by defining a master cavity adapted to form a first glass mold. A quantity of glass mold material is disposed within such cavity and molded in conformation with said master. The molding surface of each such glass mold defines an optical surface to be subsequently formed on an optical element.
