Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Axial Aberrations of Lenses Here a compromise must often be made between the center and the edge of the field. In these systems the color must be well corrected to avoid chemical focus or the blurring of the image, due to the actinic rays focusing nearer to (or farther from) the lens than the visual. Especially is the color correction important in lenses used for color photography and in process lenses. In astrographic lenses, those used in stellar photography, a field is required which is large relative to telescopic systems but small compared with lenses for ordinary photography. Over this field they are required to be corrected very accurately with regard to all aberrations, though color is of secondary importance, since a color screen, or plates which are sensitive only to a short range of the spectrum, may be used. In portrait lenses the central definition is of greater importance than that of any other part of the field, since focusing on the eyes of the sitter will give sharp definition there and produce the effect of concentrating the attention on the expression without directing it to less important details. In all cases the central definition is very important and the determination of the errors in the center of the field will generally give a comparative value of the lens. The central corrections show, with very few exceptions, the highest quality of definition a lens will give. Even in a lens with a large field, when a com promise must be made between the center and edge of the field, the central definition must be at least as good as the edge, if not better.

Download or read book Aberrations of Optical Systems written by W.T Welford and published by Routledge. This book was released on 2017-11-22 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although the subject of optical design as a branch of applied physics is over one hundred years old, the use of aberration theory has changed considerably. Aberrations of Optical Systems covers elementary optics and aberration theory of various optical systems, including the use of nonaxially symmetric systems and diffractive optical elements in complex designs, such as head-up displays and the increasing use of scanning systems with laser illumination. The book provides the complete range of mathematical tools, formulae, and derivations needed for understanding the process of optical design and for planning optical design programs. While the treatment is mainly based on geometrical optics, some excursions into physical optics are made, particularly in connection with the problems of optical tolerances.

Download or read book Aberration Theory Made Simple written by Virendra N. Mahajan and published by SPIE Press. This book was released on 1991 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a clear, concise, and consistent exposition of what aberrations are, how they arise in optical imaging systems, and how they affect the quality of images formed by them. The emphasis of the book is on physical insight, problem solving, and numerical results, and the text is intended for engineers and scientists who have a need and a desire for a deeper and better understanding of aberrations and their role in optical imaging and wave propagation. Some knowledge of Gaussian optics and an appreciation for aberrations would be useful but is not required.

Book excerpt: This handbook provides a comprehensive review of the entire field of laser micro and nano processing, including not only a detailed introduction to individual laser processing techniques but also the fundamentals of laser-matter interaction and lasers, optics, equipment, diagnostics, as well as monitoring and measurement techniques for laser processing. Consisting of 11 sections, each composed of 4 to 6 chapters written by leading experts in the relevant field. Each main part of the handbook is supervised by its own part editor(s) so that high-quality content as well as completeness are assured. The book provides essential scientific and technical information to researchers and engineers already working in the field as well as students and young scientists planning to work in the area in the future. Lasers found application in materials processing practically since their invention in 1960, and are currently used widely in manufacturing. The main driving force behind this fact is that the lasers can provide unique solutions in material processing with high quality, high efficiency, high flexibility, high resolution, versatility and low environmental load. Macro-processing based on thermal process using infrared lasers such as CO2 lasers has been the mainstream in the early stages, while research and development of micro- and nano-processing are becoming increasingly more active as short wavelength and/or short pulse width lasers have been developed. In particular, recent advances in ultrafast lasers have opened up a new avenue to laser material processing due to the capabilities of ultrahigh precision micro- and nanofabrication of diverse materials. This handbook is the first book covering the basics, the state-of-the-art and important applications of the dynamic and rapidly expanding discipline of laser micro- and nanoengineering. This comprehensive source makes readers familiar with a broad spectrum of approaches to solve all relevant problems in science and technology. This handbook is the ultimate desk reference for all people working in the field.
