Diagrams of complex reflectance or circle diagrams are used to design optical coatings at normal incidence. The technique can be extended to oblique incidence, including the design of coatings which take advantage of total internal reflectance. Use of these diagrams is helpful in visualizing and compensating for polarization effects in such coatings.
