Optical Flatness Specification at Brooke Mccann blog

Optical Flatness Specification. Surface flatness is a type of surface accuracy specification that measures the deviation of a flat surface such as that of a. Optical flats are plates with one or two surfaces of particularly high optical quality and flatness. The most common method within the flat lapping sector is by using a. The flatness of an optical flat is measured in fractions of a reference wavelength, 632.8nm. The degree of flatness is quantified with the distance between two parallel imaginary. A λ/20 flat will have a maximum peak to valley deviation of 632.8/20 or 31.64nm. Surface flatness describes the deviation between the surface of an optical filter and a perfectly flat reference plano surface. There are a number of ways to measure the flatness of a surface. Optical flats or test plates are polished surfaces that are used as references against the flatness of unknown surfaces for comparison.
