This book is the successor to High Collection Nonimaging Optics, published by Academic Press in 1989, and Optics of Nonimaging Concentrators, published 10 years earlier, by W. T. Welford and R. Winston. Walter Welford was one of the most distinguished optical scientists of his time. His work on aberration theory remains the definitive contribution to the subject. From 1976 until his untimely death in 1990, he took on the elucidation of nonimaging optics with the same characteristic vigor and enthusiasm he had applied to imaging optics. As a result, nonimaging optics developed from a set of heuristics to a complete subject. We dedicate this book to his memory.

It incorporates much of the pre-1990 material as well as significant advances ...
