Book Description
Prism and Lens Making: A Textbook for Optical Glassworkers, Second Edition is a unique compendium of the art and science of the optical working of glass for the production of mirrors, lenses, and prisms. Incorporating minor corrections and a foreword by Professor Walter Welford FRS, this reissue of the 1957 edition provides a wealth of technical information and hands-on guidance gained from a lifetime of experience. Although some of the techniques have been replaced by more modern methods, this classic book is still a valuable source of practical assistance as well as being a pleasure to read. About the Author Frank Twyman was a skilled craftsman in all aspects of optics. He joined Otto Hilger in 1898 to work on the production of simple spectroscopes costing less than £10 each. After the death of Otto Hilger, Twyman became Managing Director of Adam Hilger Ltd., a company known for the finest quality optical and mechanical work. He worked here from 1902 to 1946 and was very concerned with the practical aspects of instrument making; he designed many of the instruments himself and constantly strove to improve the techniques of optical grinding and polishing. In 1916 Twyman and Alfred Green, the foreman of the Hilger optical shops, patented the now-famous prism and lens testing interferometer that bears their names. Twyman also undertook fundamental studies in the annealing process for glass and invented new spectrophotometers and spectrographs.

Book Description
This fourth edition of Clinical Management of Binocular Vision uses the past five years of research studies and literature to provide an accurate look at today’s diagnosis and treatment of binocular vision. Written with an emphasis on proper evaluation, diagnosis, and treatment, each condition is covered in-depth and includes background information, symptoms, case analysis, and management options. This edition also includes the latest information on new vision therapy equipment. Easy to read and understand, this book is ideal for faculty when designing courses, students studying these topics for the first time, or established practitioners looking for a practical, easy-to-use reference on accommodative, ocular motility, and nonstrabismic vision anomalies.

Book Description
Entirely updated to cover the latest technology, this Second Edition gives optical designers and optomechanical engineers a thorough understanding of the principal ways in which optical components - lenses, windows, filters, shells, domes, prisms, and mirrors of all sizes - are mounted in optical instruments.Along with new information on tolerancing, sealing considerations, elastomeric mountings, alignment, stress estimation, and temperature control, two new chapters address the mounting of metallic mirrors and the alignment of reflective and catadioptric systems.The updated accompanying CD-ROM offers a convenient spreadsheet of the many equations that are helpful in solving problems encountered when mounting optics in instruments.

Book Description
The ultimate ophthalmic dispensing reference, this book provides a step-by-step system for properly fitting and adjusting eyewear. It covers every aspect of dispensing — from basic terminology to frame selection to eyewear fitting, adjusting, and repairing. Perfect for both students who are just learning about dispensing and practitioners who want to keep their skills up to date, this resource offers in-depth discussions of all types of lenses, including multifocal, progressive, absorptive, safety, recreational, aspheric, and high index. Plus, it goes beyond the basics to explore the "how" and "why" behind lens selection, to help you better understand and meet your patients' vision needs. - A glossary of key terms provides easy access to definitions. - Proficiency tests at the end of each chapter reinforce your understanding of the material through multiple-choice, fill-in-the-blank, matching, and true/false questions. - A new full-color design with hundreds of illustrations that clearly demonstrate key procedures, concepts, and techniques. - Updated coverage of the latest dispensing procedures and equipment. - Detailed information on the newest types of lenses, including progressive, absorptive, aspheric, and atoric. - Updated photos feature more current frames and lenses, keeping the book up to date with today's eye care trends.

Book Description
This text examines the various ways in which prisms and small mirrors typically are designed and mounted in optical instruments. It provides analytical tools for evaluating different designs, and discusses the advantages and disadvantages of various techniques. The book, in part, is an outgrowth of SPIE short courses taught by the author and is a companion to his 1995 volume Mounting Lenses in Optical Instruments. The work should be useful for engineers and other practitioners in the fields of optical engineering and optomechanical design.

Book Description
Clinical Optics is intended primarily for use by optometry students, though it could also prove useful for the training of optometric technicians and dispensing opticians. This book is organized into thirteen chapters. These chapters cover most aspects of ophthalmic optics or clinical optics including the design and dispensing of eyewear, the types for lenses suitable for correcting high refractive errors, the optical principles governing low vision lenses and the importance of absorptive lenses and lens coatings for eye protection against radiation. This book will be of interest to optometry students and to those involved in the training of optometric technicians and dispensing opticians.
