ISO 10110 specifies the presentation of design and functional requirements for optical elements in technical drawings used for manufacturing and inspection. This part of ISO 10110 describes rules for the indication of the surface texture of optical elements. Surface texture is the characteristic of a surface that can be effectively described with statistical methods. Typically, surface texture is associated with high spatial frequency errors (roughness) and mid-spatial frequency errors (waviness). This part of ISO 10110 is primarily intended for the specification of polished optics. This part of ISO 10110 describes a method for characterizing the residual surface that is left after detrending by subtracting the surface form. The control of the surface form is specified in ISO 10110-5 and ISO 10110-12; it is not specified in this part of ISO 10110. With regard to the previously valid 2000 edition of the standard, the scope has been extended to include waviness. Moreover, the terms and definitions have been modified and supplemented, for example, specular (optically smooth) surface has been modified to read optically smooth surface. The indications in drawings have also been partly modified, for example, for optically smooth surface textures. The committee responsible for this standard is NA 027-01-02 AA "Grundnormen für die Optik" ("Fundamental standards for optics") of the Optics and Precision Mechanics Standards Committee at DIN.
