Working models of telescopes, microscopes, photographic lenses, and optical projection systems are diagrammed and explained in full, as are the basic experiments for determining accuracy, power, angular field of view, amount of aberration, and all other necessary facts about the instrument. Throughout the book, only elementary mathematics is used, for the benefit of the student and the beginner in the field of optics.The author, an assistant professor at the Imperial College of Science and Technology in London, shows ho 410 0$aDover Books on Physics 517 $aOptics and Optical Instruments 606 $aOptics$7Generated by AI 606 $aOptical instruments$7Generated by AI 615 0$aOptics 615 0$aOptical instruments 676 $a535.33 700 $aJohnson$b B.
