Paper Abstract

The development of precision machines for generating aspheric optical surfaces at Bell & Howell Company, which were the ancestors of many of today's diamond turning machines, is outlined together with present machine capability. A practical procedure for compensating for repeatable machine position errors based upon measurement of a "best-fit" sphere is described. Applications of diamond turning to reflective and transmissive (germanium and silicon) infrared optical elements are illustrated.
