WebMar 14, 2024 · The irregularity specification is used to describe the deviation of a test surface’s shape from the shape of its corresponding reference surface. The measurement is obtained using the same test conducted for power, but this test focuses on the sphericity of the circular fringes, which are determined by comparing the test and reference surfaces. WebIrregularity, a type of surface accuracy specification, describes how the shape of a surface deviates from the shape of a reference surface. It is obtained from the same measurement as power. Regularity refers to the sphericity of the circular fringes that are formed from the comparison of the test surface to the reference surface.
