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 Although some of the techniques have been
replaced by more modern methods, this classic book is still a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.
