The 242-page book Practical Equipment, Materials, and Processes for Optical Thin Films details the equipment, materials and processes used in the fabrication/production of optical thin films. It focuses on the practical elements involved in producing the films and aims to provide a basic understanding of the function and operation of the equipment and the behavior of the materials when produced by the various processes. Techniques, real-life examples and suggestions are offered to help develop, debug or refine the processes with a minimum number of test runs. Chapters cover such areas as evaporation sources, temperature control, measuring spectral results in the real world, film growth models and observations, ion sources, physical and chemical vapor deposition, plasma polymerization and experiment methodology.
