Optical flats are used for testing and evaluating other optical elements. An interference pattern is formed in the air between the flat and the object being evaluated, and this pattern is usually more seen through the flat than through the object. The pattern consists of alternating bright and dark bands or fringes which are a contour map of the thickness of the air film. If the surface of the optical is significantly flatter than the surface being evaluated, it is correct to interpret the interference pattern directly as a contour map of the surface being evaluated.
