    Single side optical flat,Double side optical flat,Optical Parelle.

    Measuring the evenness and depth of parallelism

    The evenness error of grade - one optical flat is no lager than 0.03 μm ,

    and the evenness error of grade-2 is no larger than 0.01μm

    Specififcations of optical flat:

    (a) Measuring face evenness error : smaller than 0.03μm for grade - one smaller than 0.10μm for grade - two

    (b) Depth of parallelism error : smaller than 0.20μm

    (c) External diameter : 30mm

    (d) Thickness : 12.00mm , 12.12mm . 12.25mm . 12.37mm

          The set of four optical parallel flats can be used to measure the parallelism depth deviation

          of the milscale's two opposite measurement planes ; The deviants in four directions including

          0° , 90° , 180° and 270° can be obtained Specification:φ30,φ45,φ60.
