This paper describes various types of anti-reflection coatings, how they work, and their use in optical systems. Examples are given of design types available for the visible spectrum. The use of anti-reflection coatings at non-normal incidence is discussed and practical limitations considered. A brief review of the state-of-the-art in wideband anti-reflection coatings is presented.
