Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

A complete optical systems design course for general optical engineers! Practical optical system layout. The ``first cut'' design of an optical system--anything from a telescope to a complicated VR helmet--is usually not done by a specialist but by a more general optical engineer. This book, drawn from the author's extensive seminar experience, details such basic design techniques in a clear, concise, ``low-math'' way that is sure to be readily accessible to anyone with a working knowledge of optics. It discusses the characteristics of a wide range of optical components, how to determine the type of components to be used, and how to arrange these components so that the system measures up to its performance objectives. Practical, step-by-step coverage includes succinct equations, simple diagrams, and clear explanations. For less experienced designers, the chapter on utilizing stock lenses (to test a concept or to prove out a possible finished device) should be especially useful.

Excerpt from General and Practical Optics The incandescence of the sun is, of course, the principal source from which light on the earth is derived. Impact, friction, electricity, chemical combination, combustion, in fact anything which causes increased molecular motion, also may give rise to light.
