Optical Paralell

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.
