One has to get used to Kingslake s terminology However then, you will find this book really great.I could find a lot of interesting notes and calculation which I do not find in other optics textbooks. Lens Design Fundamentals, Second Edition, is the most comprehensive treatise to be published on the subject of Lens Design This book holds a unique place in the optics literature It adds impressive building blocks to the foundation established by A E Conrady in Applied Optics and Optical Design and Rudolph Kingslake in Lens Design Fundamentals, First Edition Dr R Barry Johnson is a disciple of Conrady and Kingslake, and who has a deep background in lens design theory as a Professor of Optics and many years of experience as a practicioner in the real world of lens design Thus, he is ideally suited to write an up to date edition of Lens Design Fundamentals This new edition has been extensively rewritten and expanded by about 50% in both text and figures.Dr Johnson takes the reader from the work of the lens designer into ray tracing methods and First Order Optics This is followed by three chapters on aberration theory which provide the foundation for the subsequent chapters which follow on the design of different types of lens systems that form the basis of most modern lenses, including zoom lenses One entire chapter is devoted to the role of the Stop in lens design Dr Johnson also devotes a chapter to Mirror and Catadioptric Systems, an important class of optical system largely neglected in books on Optics The final chapter is devoted to Automatic Lens Improvement Programs In this treatise Dr Johnson stresses the need for an understanding of lens design principles and aberration theory as a prerequisite to obtaining the best solutions from these optimization programs.The value of Lens Design Fundamentals, Second Edition, is increased immensely by the numerous examples presented throughout as well as by Designer Notes interspersed in each chapter For its audience this treatise is intended for the beginner through each intermediate level of experience up to and including the expert lens designer This book will be a very valuable addition to any bookshelf. If one is after the detailed mathmatics of optical design, this is a good book. If you thumb through this bad boy, you ll notice that there s a lot of raytracing going on Consequently, this is a great book from which to learn about raytracing, specifically the y nu or ynu paraxial method I made the effort of setting up a ynu table in Excel and used the equations to trace chief and marginal rays with much success along with first order properties such as focal length, F , entrance exit pupil position radius, et cetera I then used the computed data and generated a lens drawing with traced rays, all in Excel A Delano y ybar diagram was inserted next, followed by computation of the Seidel aberration coefficients Use the book with Excel and you ll find it incredibly useful.In addition to the raytracing, Kingslake discusses chromatic aberration, primary spectrum and secondary spectrum in detail Also writes about the Seidel aberrations and how to compute them, using various sample lenses.A great complement to A History of the Photographic Lens and Optics in Photography, both of which are quite informative regarding lens types and principles. Thoroughly revised and expanded to reflect the substantial changes in the field since its publication in 1978 Strong emphasis on how to effectively use software design packages, indispensable to todays lens designer Many new lens design problems and examples ranging from simple lenses to complex zoom lenses and mirror systems give insight for both the newcomer and specialist in the field Rudolf Kingslake is regarded as the American father of lens design his book, not revised since its publication in 1978, is viewed as a classic in the field Naturally, the area has developed considerably since the book was published, the most obvious changes being the availability of powerful lens design software packages, theoretical advances, and new surface fabrication technologies This book provides the skills and knowledge to move into the exciting world of contemporary lens design and develop practical lenses needed for the great variety of 21st century applications Continuing to focus on fundamental methods and procedures of lens design, this revision by R Barry Johnson of a classic modernizes symbology and nomenclature, improves conceptual clarity, broadens the study of aberrations, enhances discussion of multi mirror systems, adds tilted and decentered systems with eccentric pupils, explores use of aberrations in the optimization process, enlarges field flattener concepts, expands discussion of image analysis, includes many new exemplary examples to illustrate concepts, and muchOptical engineers working in lens design will find this book an invaluable guide to lens design in traditional and emerging areas of application it is also suited to advanced undergraduate or graduate course in lens design principles and as a self learning tutorial and reference for the practitioner Rudolf Kingslake 1903 2003 was a founding faculty member of the Institute of Optics at The University of Rochester 1929 and remained teaching until 1983 Concurrently, in 1937 he became head of the lens design department at Eastman Kodak until his retirement in 1969 Dr Kingslake published numerous papers, books, and was awarded many patents He was a Fellow of SPIE and OSA, and an OSA President 1947 48 He was awarded the Progress Medal from SMPTE 1978 , the Frederic Ives Medal 1973 , and the Gold Medal of SPIE 1980 R Barry Johnson has been involved for over 40 years in lens design, optical systems design, and electro optical systems engineering He has been a faculty member at three academic institutions engaged in optics education and research, co founder of the Center for Applied Optics at the University of Alabama in Huntsville, employed by a number of companies, and provided consulting services Dr Johnson is an SPIE Fellow and Life Member, OSA Fellow, and an SPIE President 1987 He published numerous papers and has been awarded many patents Dr Johnson was founder and Chairman of the SPIE Lens Design Working Group 1988 2002 , is an active Program Committee member of the International Optical Design Conference, and perennial co chair of the annual SPIE Current Developments in Lens Design and Optical Engineering Conference Thoroughly revised and expanded to reflect the substantial changes in the field since its publication in 1978 Strong emphasis on how to effectively use software design packages, indispensable to todays lens designer Many new lens design problems and examples ranging from simple lenses to complex zoom lenses and mirror systems give insight for both the newcomer and specialist in the field
