The practical, popular 1995 tutorial has been thoroughly revised and updated, reflecting developments in technology and applications during the past decade. New chapters address wave aberrations, thermal effects, design examples, and diamond turning.
The many positive remarks about the first edition and listening to the feedback from the students over the past five years encouraged me to expand upon the original material in this second edition.
To that end, the subject of beam expanders was modified, and achromats have been covered in more detail. In a chapter on Special Optical Surfaces and Components, the ball lens, gradient optics, and three-mirror configurations have been added.
New chapters are Wave Aberrations, Thermal Effects, Design Examples, and
Diamond Turning. In Wave Aberrations, besides the concept, comparison of spherical aberration with the Seidel coefficient is discussed. The chapter Thermal Effects deals with methods of designing athermats, lenses that compensate for the undesired results caused by temperature excursions. The chapter Design Example is an application-based summary of the subjects covered in the earlier chapters of the book. Because diamond turning is especially suitable for producing aspheres and diffractive infrared elements, a chapter has been added to describe this manufacturing method.
To follow the style of the first edition, the added material contains practical
approaches with approximations and many numerical examples.
I thank Rick Hermann and Sharon Streams of SPIE for their support and editorial assistance. I also thank my friend and colleague Robert E. Fischer for reviewing this second edition. His suggestions have been most valuable.
