Optical Workshop Principles

Abstract

IT may at first sight seem surprising that a second book on the grinding and polishing of lenses should have been published by Hilger's so soon after their publication of "Prism and Lens Making" by Mr. Twyman. But there are at least two reasons which justify such a course. In the first place, lens-making is a craft, and each craftsman's account of his experience has something of value to every other craftsman. In the second place, the author is a Frenchman, and it is much to be desired that information about the techniques employed in one country should be made available in other countries. It is a novel experience to find the names of pioneers turn out to be names of Frenchmen rather than Britons, while the sources of specially suitable material or apparatus are quoted as French rather than English.
