Full title and description

ISO 10110-6:2025 — Optics and photonics — Preparation of drawings for optical elements and systems — Part 6: Centring and tilt tolerances. This part of the ISO 10110 series specifies rules and graphical indications for stating centring and tilt tolerances on technical drawings of optical elements, subassemblies and complete assemblies.

Abstract

This document provides the rules for indicating centring and tilt tolerances for optical elements, subassemblies and assemblies within the ISO 10110 drawing notation system. It applies to plano, rotationally invariant (spherical and aspherical), circular and non‑circular cylindrical surfaces, and general (non‑symmetrical) surfaces (the latter are described with reference to ISO 10110‑19).

Scope

ISO 10110‑6:2025 defines the conventions and presentation for centring and tilt tolerances on drawings of optical components and assemblies. It is intended to be used with other parts of the ISO 10110 series and covers a wide range of surface types (plano, spherical/aspherical, cylindrical/acylindrical and general surfaces — see ISO 10110‑19 for non‑symmetrical surface description).

Key topics and requirements

• Rules for indicating centring tolerances (graphical notation and numerical specification) on optical drawings.
• Rules for indicating tilt tolerances (angular orientation limits and related notation).
• Application to multiple surface geometries: plano, rotationally invariant (spherical/aspherical), circular and non‑circular cylindrical, and general surfaces (reference to ISO 10110‑19).
• Conformance with the ISO 10110 drawing system so that manufacturing and inspection documentation use consistent symbols and tolerance definitions.

Typical use and users

Used by optical designers, mechanical engineers, drawing/drafting specialists, quality and metrology engineers, manufacturing engineers and procurement specialists to specify and interpret centring and tilt requirements for lenses, prisms, mounts and assembled optical systems. It is applied where consistent, unambiguous drawing indications for alignment tolerances are required for production and inspection.
