Modern lens design programs make it possible to thoroughly study alternative designs. A study of this type has been made on a Heliar and an aspheric Triplet. It is now becoming possible to define regions of solution and set standards of performance. We are now able to accurately predict performance of lenses and are beginning to tackle problems of setting tolerances. The use of aspheric surfaces has been retarded because of their expense. The large computer with modern data acquisition equipment may eventually also solve the aspheric generation problem.
