A simple method is described for quickly and easily designing high-performance optical systems. It involves little iteration, if any, and requires neither a computer nor extensive hand calculations. The systematic application of this design method allows one to construct configurations where the function of every surface is clearly understood. As a result, new design configurations tend to suggest themselves to the designer. This insight, which is an integral part of the design method to be described, also makes it clear how to compound designs so as to extend the f/# and/or field of view over which high performance is obtained. Although the design method only uses well-known principles of aberration control, it combines them and systematically applies them in a particular way that has not gained the wide use it merits. Several design examples illustrate how this design method is applied. They include a telephoto lens, an inverse telephoto lens, a fisheye type lens and a catadioptric system.
