Optics and photonics. Preparation of drawings for optical elements and systems - Surface texture1 Scope This document specifies rules for the indication of the surface texture of optical elements, in the ISO 10110 series, which standardizes drawing indications for optical elements and systems. 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
