ABSTRACT:
A method of forming a sharp edge on an optical device. The method involves the steps of placing the optical device in a holding mechanism; grinding one surface of the optical device so the one surface and a surface of the holding mechanism are co-planer; and polishing the one surface of the optical device and the surface of the holding mechanism with felt until an edge on the one surface of the optical device adjacent the surface of the holding mechanism obtains a desired sharpness.
