ABSTRACT
This book is intended to form an introduction to thin-film optical filters for both the manufacturer and the user. It does not pretend to present a detailed account of the entire field of thin-film optics, but it is hoped that it will form a supplement to those works already available in the field that only briefly touch on the principles of filters. For the sake of a degree of completeness, it has been thought desirable to repeat some of the information that is found elsewhere in textbooks, referring the reader to more complete sources for greater detail. The topics covered are a mixture of design, manufacture, performance, and application, including enough of the basic mathematics of optical thin films to enable the reader to carry out thin-film calculations. The aim has been to present, as far as possible, a unified treatment, and there are some alternative methods of analysis that are not discussed.
