Optical Flats

An optical flat is a piece of glass, pyrex, or quartz having one or both surfaces carefully ground and polished plano, generally flat to less than a tenth of a wavelength. Optical flats are used in surface testing to determine the flatness of other optical surfaces using interference techniques.
