An excellent update to an excellent book. A comprehensive handbook on optical design and geometrical optics that covers the basic theory as well as practical details. -James C. Wyant, College of Optical Sciences, University of Arizona, USA Even with modern 'easy-to-use' lens design software and global optimization, the understanding of aberration theory ... Read moreis essential to finding high-performing cost-effective design solutions. This book not only teaches the students the basics of aberration theory but adds in the needed understanding of higher order aberrations for modern optical systems. The chapter on wavefront aberrations and Zernike polynomials has been greatly improved and follows a notation becoming a standard in the industry. -Dr. Julie L. Bentley, University of Rochester, New York, USA This is a new edition of a book that has been used in the course of lens design by the authors for many years. So it covers many aspects of optics taking in the progress in the individual field. Also the authors are trying to make the students of the course changing the order of materials as well as adding new ones. -Kyoji Nariai, National Astronomical Observatory of Japan, Mitaka, Tokyo Praise for Previous Editions Many helpful references are given at the end of each chapter and the appendices, and these have been expanded from the first edition. ... Overall, the changes made in this edition have enhanced the book's value as an important reference for the optics community. -Optics and Photonics News, Feb. 2006 ... the book makes liberal use of figures and diagrams, and covers both the basic principles of geometrical optics as well as their application to lens design. ... this book is recommended for academic libraries with active programs in optical engineering, and certainly for libraries owning well-used copies of the first edition. -E-Streams, Vol. 7, No. 5, May 2004 I found the book to be well presented and easy to read. ... For those interested in optical systems, this is a useful book to have on hand. -The Physicist, Vol. 41, No. 2, March/April 2004 Not only the basic theory is treated in this book, but many practical details for the design of important optical systems are given. ... [A] book which is important and helpful and should not be missed in any optical laboratory. -Optik-International Journal for Light and Electron Optics, Vol. 115, No. 10, 2004 Show Less
