Abstract
A method of forming one or more optical surfaces of the designer's choice in a body of material. The method includes the steps of exposing in a work zone a selected face in a body of selected material, directing a focused ion beam in a predetermined manner into the work zone to impinge the selected face, and by such directing and impinging, removing material from the body to create the desired optical surface(s). Preferably, beam direction is accomplished under the control of a suitably programmed computer.
