Abstract
For a long time lens designers have recognised the desirability of using aspheric optical surfaces for some applications, and recently there have been significant advances in the manufacturing technology for such surfaces. Nevertheless, there is reluctance on the part of manufacturers to install the appropriate equipment unless sufficient advantage can be achieved. The three main methods of aspheric surface manufacture (figuring of spherical surfaces, numerically-controlled machining, and moulding) are briefly reviewed. Design examples of infrared and visible light optical systems are given to show that each of these manufacturing methods can be used to produce lenses incorporating aspheric surfaces that have distinct advantages over the equivalent lens with only spherical surfaces. The manufacturing method must be matched to the system needs and performance requirement.
