Paper Abstract

The manufacture of aspheric optical surfaces presents both technical difficulties and unique opportunities. Military systems will see increasing use of the aspheric optical surface due to improved function and reduced system cost. This paper first summarizes the strengths and weaknesses of present diamond turning technology. The requirements of manufacturing precision aspherics in sufficient volume to be cost effective are shown in terms of the turning, polishing and gaging machines necessary for production. The remainder of the paper discloses how machine control features using programmed micro-electronics allows a completely new approach to surfacing precision aspherics.
