    multifocal contact
  • (Multifocal contacts) these lenses are designed to provide both distance vision and reading vision for those who have presbyopia. There are several styles to choose from depending on your needs.
    lens design
  • Optical lens design refers to the calculation of lens construction parameters (variables) that will meet a set of performance requirements and constraints, including cost and schedule limitations.
  • the factors of an optical lens (other than the prescription) which determine how it is going to function; level of satisfaction is determined by your dispenser's ability to advise you about options not specified by the prescription that are available and will potentially meet your particular

Lens Design Fundamentals, Second Edition
Lens Design Fundamentals, Second Edition
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 today's 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 much more.
Optical 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.

Kodak Bantam f/12,5 Doublet Lens
Kodak Bantam f/12,5 Doublet Lens
Kodak did battle against their own 35mm cartridge with a new variation on 35mm film they called 828. The first camera offered in this format was the original Kodak Bantam, shown a in is cheaper version with a folding finder and an f/12.5 lens. There is an air of family with the Baby Brownie and unquestionable Bullet (all design by W.D. Teague). Features: Film Size: 828 Shutter: I Lens: Doublet f/12.5 Dates: 1935-1938 Design by: Walter Dorwin Teague Kodak dio la batalla contra su propio cartucho de 35mm con una nueva variante de pelicula de 35mm, el formato 828. La primera camara que se ofrece en este formato fue la original Kodak Bantam, en diversas variantes. La aqui mostrada es una version mas barata con un visor plegable, objetivo con f/12.5 . El aire de familia con la Baby Brownie o la Bullet, es incuestionable (por que todas fueron disenadas por W.D. Teague). Caracteristicas: Tamano pelicula: 828 Obturador: velocidad I (unica) Objetivo: f/12.5 Doublet Fechas: 1935-1938 Disenada por: Walter Dorwin Teague

Modern Lens Design (McGraw-Hill Professional Engineering)
Unlike the first edition, which was more a collection of lens designs for use in larger projects, the 2nd edition of Modern Lens Design is an optical “how-to.” Delving deep into the mechanics of lens design, optics legend Warren J. Smith reveals time-tested methods for designing top-quality lenses. He deals with lens design software, primarily OSLO, by far the current market leaders, and provides 7 comprehensive worked examples, all new to this edition. With this book in hand, there’s no lens an optical engineer can’t design. (20050601)
