An optical flat is an optical-grade piece of glass lapped and polished to be extremely flat on one or both sides, usually within a few tens of nanometres (billionths of a metre). They are used with a monochromatic light to determine the flatness (surface accuracy) of other surfaces, whether optical, metallic, ceramic, or … See more An optical flat is usually placed upon a flat surface to be tested. If the surface is clean and reflective enough, rainbow colored bands of interference fringes will form when the test piece is illuminated with white light. However, … See more Counterintuitively, the fringes do not exist within the gap or the flat itself. The interference fringes actually form when the light waves all … See more Wringing occurs when nearly all of the air becomes forced out from between the surfaces, causing the surfaces to lock together, partly … See more During reasonable care and use, optical flats need to maintain their flatness over long periods of time. Therefore, hard glasses with low coefficients of thermal expansion, such as See more The diagram at right shows an optical flat resting on a surface to be tested. Unless the two surfaces are perfectly flat, there will be a small gap … See more Absolute flatness is the flatness of an object when measured against an absolute scale, in which the reference flat (standard) is completely free of irregularities. The … See more The fringes act very much like the lines on a topography map, where the fringes are always perpendicular to the wedge between the surfaces. When wringing first begins, there is a … See more
