Abstract
A tool for producing a pattern of highly accurate and optical quality surfaces and the method of making same from a series of bi-metallic pins. A high strength metal pin is coupled to a slug of metal of lesser strength capable of being accurately scribed. The supporting pin blank preferably is magnetic stainless steel and the slug is of copper. A group of such bi-metallic pins then is placed in an appropriate fixture after which an optical configuration, such as the three faces of a cube-corner element, are scribed into the copper ends. A completed tool may then be electroformed to produce an electroformed tool from an array of like or different pins, arranged in various patterns.
