Optical coatings are thin layers of material applied to the surface of optical elements, like lenses and mirrors, to enhance their performance in transmitting, reflecting, or filtering light. These coatings can significantly modify how light interacts with surfaces, making them critical for applications in imaging systems, lasers, and optical devices. The effectiveness of these coatings is often analyzed using principles from the Fresnel equations and is influenced by phenomena such as Brewster's angle.
congrats on reading the definition of optical coatings. now let's actually learn it.
