Abstract
Single point diamond turning (SPDT) is a cost effective method of making severe aspherics in metal. This is particularly true in multi-element systems where accurate mating surfaces can be turned in the same set-up with the optically active surfaces. With current SPDT machines, such aspherics perform satisfactorily in the infrared but tend to scatter sufficient light in the visible that it is difficult to impossible to obtain an assessment of system alignment and image quality using visible light test equipment.
