WebMay 11, 2013 · We carried out the three-flat test for an absolute calibration of optical flats by considering the effect of a relative humidity change. The calibration results indicate that the uncertainty in the measurements of the Fizeau interferometer was successfully improved to 0.7 nm ( σ : standard deviation) along a length of more than 145 mm. 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 otherwise, by interference. When an optical flat is placed on anothe…
