Ultraviolet Radiation [antikvár]

Preface There is a great wealth of information available in the scientific and technical literature covering every aspect of ultraviolet radiation. However, it is often very difficult for the nonspecialist in the field of radiation to find the information he requires. This book is intended to answer some of the questions which confront physicists and speciaUsts in fields other than physics when they find it necessary to work in this portion of the spectrum. Its preparation was prompted by many inquiries from physicists, biologists, medical men, chemists, engineers, and laymen over the course of the years. It does not make the slightest pretence at being comprehensive or all-inclusive, but merely treats of those matters which seem to me to have been of most importance to people who are attempting to utilize radiation at the short-wave end of the spectrum. It has been necessary to describe various commercial arcs. These have been selected in general as illustrative of certain types of discharges. A catalog of lamps was not intended. Obviously such a catalog would rapidly become obsolete, and this kind of information can readily be obtained from the many reputable manufacturers. However, it was my thought that the descriptions given would be of some help in guiding the user in the proper direction. The chapters on reflection and transmission obviously do not cover the performance of all materials but, for the most part, only of those which are commonly used and readily available. The section on applications is limited to those which have interested me most and in which certain basic principles are involved.
