5.1 About the Sample Lens Designs

One of the features of this volume is a fairly large set of lens designs, their prescriptions, and their aberration plots. This set is not intended to be a complete or extensive collection of all or even most of the published lens designs. We happily leave that to others. The set is intended to be a selection of lens designs that will serve two primary purposes. These are to serve as a set of suitable starting designs and also to serve as a set of designs that illustrate to the reader the principles and techniques of successful lens designs.

In this second edition of Modern Lens Design we have pruned out about half of the lens designs featured in the first edition. This was done (among ...
