A stronomy, Photography, andS pectroscopy, have -frequently expressed the desire for a simple theoretical account of those defects of performance of optical instruments to which the names comaj cwrvature of fields astigmatism, distortion secondary spectrum want of resolving power, etc., are given :it is hoped that the need will to some extent be met by this little work, in which the endeavour is made to lead up directly from the first elements ofO ptics to those parts of the subject which are of greatest importance to workers with optical instruments. A short account of the principal instruments has been added. While the tract is primarily written with this practical aim, the writer ventures to hope that it may be useful in drawing the attention of Pure Mathematicians to some, attractive theorems: of special interest is Klein sapplication of the imaginary circle at infinity to establish the result (30) that no optical instrument can possibly be constructed, other than the plane mirror, so as to be capable of transforming all the points of the object-space into points of the image-space. The writer moreover believes that the customary course of Geometrical Optics presented to mathematical students in Universities might with advantage be modified: and ofiers the present tract as a suggestion to this end.

Paperback. Etat : New. Print on Demand. This book by the renowned astronomer E. T. Whittaker is an accessible guide to the theory of optical instruments. Beginning with the fundamentals of geometrical optics, the author leads the reader through the construction and function of lenses, mirrors, and other optical instruments. Key topics include primary and secondary foci, image formation, astigmatism, distortion, chromatic aberration, and resolving power. The author assumes no prior knowledge of mathematics beyond the basics of geometry and trigonometry. The text is clearly written and well-illustrated, making it an ideal resource both for students of astronomy and photography and for practicing instrument makers. Whittaker's thoughtful and rigorous approach provides readers with a thorough understanding of how optical instruments work and how to use them effectively in their own work. The insights gained by working through this book will greatly enhance the reader's ability to select the right instruments for a given task and to get the most out of them. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
