Entirely rewritten from the first edition, this reference and textbook presents design guidelines and their daily applications in real environments. The focus is on examples of components, subassemblies, and structures used in a wide variety of situations. New to this edition is an appendix summarizing the environmental tests to be performed on optical instruments, greater coverage of the characteristics of materials, a more detailed treatment of mountings for individual and multiple lenses, prisms, and mirrors, and more on the design of metallic and nonmetallic mirrors and optical instrument structures.
