ISO 10110-6:2025

This document specifies the rules for indicating centring and tilt tolerances for optical elements, subassemblies, and assemblies in the ISO 10110 series, which standardizes drawing indications for optical elements and systems. This document applies to plano surfaces, rotationally invariant (spherical and aspherical) surfaces, circular and non-circular cylindrical (cylindrical and acylindrical) surfaces, and non-symmetrical surfaces (general surfaces). General surfaces are described using ISO 10110-19.
