Full title and description

ISO 10110-5:2015 — Optics and photonics — Preparation of drawings for optical elements and systems — Part 5: Surface form tolerances. This part of ISO 10110 defines the graphical presentation and rules for specifying tolerances for surface form deviation on technical drawings used for the manufacture and inspection of optical elements and systems.

Abstract

ISO 10110-5:2015 specifies how to indicate design and functional requirements for surface form (surface figure) on drawings for optical elements and systems. It sets out rules for indicating tolerances, preferred units (nanometres), and allows interferometric fringe spacings provided the base wavelength is stated. The part applies to plano, spherical, aspheric, circular and non-circular cylindrical, toric and other non‑spherical surfaces, and excludes diffractive, Fresnel and micro‑optical surfaces.

Scope

Specifies rules for indicating tolerances for surface form deviations on technical drawings for optical elements and systems. Applies to plano, spherical, aspheric, circular and non‑circular cylindrical, toric and other non‑spherical surfaces used in optics and photonics. Does not apply to diffractive surfaces, Fresnel surfaces, or micro‑optical surfaces. The standard emphasizes use of nanometres as the preferred unit for expressing surface form deviations while still permitting fringe spacings when the base wavelength is declared.

Key topics and requirements

• Graphical symbols and notation for specifying surface form tolerances on optical drawings.
• Rules for expressing surface form deviation tolerances (preferred use of nanometres; allowance for interferometric fringe spacings with base wavelength stated).
• Coverage of surface classes: plano, spherical, aspheric, cylindric (circular and non‑circular), toric and generally described non‑spherical surfaces.
• Explicit exclusions: diffractive, Fresnel and micro‑optical surfaces are outside the part’s scope.
• Interaction with measurement and test methods (interferometric and non‑interferometric) and the implication for tolerance specification.

Typical use and users

Used by optical designers, mechanical designers of optical assemblies, drawing drafters, manufacturing engineers, quality and metrology engineers, contract manufacturers, and standards committees to communicate surface figure requirements unambiguously on drawings and inspection documentation. It is referenced when preparing manufacturing drawings, inspection plans, and procurement specifications for lenses, mirrors and other precision optical components.

FAQ

Q: What is this standard?

A: ISO 10110‑5:2015 is Part 5 of the ISO 10110 series and provides rules and graphical notation for specifying surface form (surface figure) tolerances on technical drawings for optical elements and systems.

Q: What does it cover?

A: It covers how to indicate tolerances for surface form deviation for plano, spherical, aspheric, circular and non‑circular cylindrical, toric and other non‑spherical surfaces, and it explains preferred units and options for expressing tolerances (nanometres preferred; interferometric fringe spacings allowed if base wavelength is given). It excludes diffractive, Fresnel and micro‑optical surfaces.

Q: Who typically uses it?

A: Optical designers, mechanical designers for optical systems, drawing drafters, manufacturing and metrology engineers, inspection and quality teams, standards committees, and suppliers of precision optics. It is used to ensure consistent interpretation of drawing tolerances between designers, manufacturers and testers.

Q: Is it current or superseded?

A: The 2015 edition is the current published edition; as of the latest ISO records the part is under revision and a Final Draft International Standard (ISO/FDIS 10110‑5) has been registered for approval and will replace ISO 10110‑5:2015 when approved. Users should check the ISO catalogue or their national standards body for the absolute latest status before relying on a dated status.

Q: Is it part of a series?

A: Yes — it is one part of the ISO 10110 series (Preparation of drawings for optical elements and systems). Other parts address general rules, surface texture, data tables, surface imperfections, centring and related drawing practices.

Q: What are the key keywords?

A: Key keywords are: surface form tolerances, surface figure, interferometry, fringe spacings, nanometres, asphere, toric, optical drawings, metrology, ISO 10110.
