Ultraviolet and Infrared Engineering

This book was written primarily for engineers. It takes up in succession the sources of ultraviolet and infrared radiation, devices for their detection and measurement, types of generators, and methods of producing phosphorescence and fluorescence. A large part of the book is devoted to engineering applications of both types of radiation, such as accelerated weathering and sterilization of air and water by ultraviolet and rapid drying methods with infrared in the paint, carpet, leather, and clay industries, among others. Machinery used for these purposes is described at some length. There is very little of immediate interest to the average dermatologist. For those especially concerned with ultraviolet radiation there is considerable technical information about such matters, for example, as ultraviolet emission from various types of mercury, xenon and carbon arc lamps, and absorption characteristics of plastic and other materials. A number of statements are open to question, such as the one
