Interference coatings are an essential part of modern optics. This book is designed to give a concise but complete overview of the field, with contributions written by leading experts in the various areas. Topics include design, materials, film growth, deposition including large area, characterization and monitoring, and mechanical stress. The authors also describe applications in astronomy, microcomponents, DUV/VUV, EUV/X, ultrafast optics, displays, and ultrasensitive fluorescence. Furthermore, laser-resistant coatings and coatings for free-electron lasers and plastic optics are covered. The book concludes with chapters on photonic structures as interference devices and on the brilliant world of natural coatings.
