General And Practical Optics PDF Download

Excerpt from General and Practical Optics In this third edition of "General and Practical Optics" I trust that some of the faults of previous editions will be found remedied. The subject-matter has been revised, condensed, rearranged, and rewritten, to some extent, and considerable fresh matter has been introduced. Although primarily intended as a textbook for candidates for the examination of the Worshipful Company of Spectacle Makers, it is written also as a reference book for those engaged in spectacle work, for other students of Optics, and as an introduction to the study of more advanced works. In previous editions I acknowledged my indebtedness to Dr. George Lindsay Johnson and to Mr. H. Oscar Wood. Here again, and to an increased extent, I repeat my recognition of the invaluable co-operation of Mr. Wood in compiling and writing the subject-matter, and in revising and correcting the work. As stated before, I have endeavoured to cover, in this book and in "Visual Optics and Sight-Testing," all that is essential for the sight-testing optician.
