Optics: Eighth Edition covers the work necessary for the specialization in such subjects as ophthalmic optics, optical instruments and lens design. The text includes topics such as the propagation and behavior of light; reflection and refraction - their laws and how different media affect them; lenses - thick and thin, cylindrical and subcylindrical; photometry; dispersion and color; interference; and polarization. Also included are topics such as diffraction and holography; the limitation of beams in optical systems and its effects; and lens systems. The book is recommended for engineering students who are in need of an introduction to the subject and the mathematics involved in it.

The Eye, Volume 4: Visual Optics and the Optical Space Sense provides a well-integrated and authoritative account of the physiology of the eye. The book is organized into two parts. Part I on visual optics begins with a discussion of the branches of optics and the basic principles of geometrical optics. This is followed by separate chapters on refraction at plane and spherical surfaces; the thin spherical lens in air; reflexion at plane and spherical surfaces; the astigmatic lens; aberrations of optical images; ametropia and its correction; and retinoscopy and ophthalmoscopy. Part II on the optical space sense includes discusses of objective and subjective space; spatial localization according to direction; perception of distance and of size; spatial localization through binocular vision; special topics in binocular spatial localization; and ocular dominance and binocular retinal rivalry. Whilst the emphasis has been on readability rather than exhaustiveness, the various accounts are sufficiently well documented to make the treatise valuable not only to teachers in physiology, psychology and ophthalmology, but also to research workers in all branches of ocular physiology.

Prism and Lens Making: A Textbook for Optical Glassworkers, Second Edition is a unique compendium of the art and science of the optical working of glass for the production of mirrors, lenses, and prisms. Incorporating minor corrections and a foreword by Professor Walter Welford FRS, this reissue of the 1957 edition provides a wealth of technical information and hands-on guidance gained from a lifetime of experience. Although some of the techniques have been replaced by more modern methods, this classic book is still a valuable source of practical assistance as well as being a pleasure to read. About the Author Frank Twyman was a skilled craftsman in all aspects of optics. He joined Otto Hilger in 1898 to work on the production of simple spectroscopes costing less than £10 each. After the death of Otto Hilger, Twyman became Managing Director of Adam Hilger Ltd., a company known for the finest quality optical and mechanical work. He worked here from 1902 to 1946 and was very concerned with the practical aspects of instrument making; he designed many of the instruments himself and constantly strove to improve the techniques of optical grinding and polishing. In 1916 Twyman and Alfred Green, the foreman of the Hilger optical shops, patented the now-famous prism and lens testing interferometer that bears their names. Twyman also undertook fundamental studies in the annealing process for glass and invented new spectrophotometers and spectrographs.
