ISO 10110-3-1996 PDF

Full title and description

ISO 10110-3:1996 — Optics and optical instruments — Preparation of drawings for optical elements and systems — Part 3: Material imperfections — Bubbles and inclusions. Specifies how to present design and functional requirements on technical drawings for optical elements and how to indicate acceptable levels and sizes of bubbles and inclusions.

Abstract

This part of ISO 10110 defines the notation and presentation rules used on optical drawings to specify permissible bubbles and other inclusions in optical elements (notation format N x A, where N is the allowed count and A is a size parameter related to the square root of projected area). It provides definitions, preferred size values, and guidance for indicating acceptability for manufacturing and inspection purposes.

Scope

ISO 10110-3:1996 prescribes the graphical and textual indications to be used on drawings to communicate acceptable levels of bubbles and inclusions in optical elements. It addresses how to specify counts and maximum sizes (using the N x A form), defines terms (bubbles, inclusions), and gives preferred numerical values for size classes to ensure consistent interpretation between designers, manufacturers and inspectors. The technical content has since been consolidated into a later part that covers multiple material-imperfection categories.

Key topics and requirements

• Notation for permissible bubbles/inclusions: N x A (N = permitted number; A = grade size equal to sqrt(projected area) in mm) and preferred A values.
• Definitions and distinctions between bubbles and other inclusions (knots, crystals, sand, etc.).
• Presentation rules for drawing callouts so manufacturing and inspection interpret acceptability consistently.
• Guidance on when bubbles/inclusions are objectionable (for example, near image planes or when scattering/visibility is critical).
• Relationship to other ISO 10110 parts (material imperfections are handled elsewhere in the consolidated Part 18).

Typical use and users

Used by optical designers, mechanical designers preparing lens/optical drawings, manufacturing engineers, metrology and QA personnel, optical material suppliers, and standards/technical authors who need unambiguous drawing callouts for bubbles and inclusions. The standard helps ensure consistent specification and acceptance criteria across the supply chain.

Related standards

ISO 10110 is a multipart series; parts of closest relevance include ISO 10110-1 (General), ISO 10110-2 (stress birefringence), ISO 10110-4 (inhomogeneity and striae) — many of these were later consolidated into ISO 10110-18:2018 (stress birefringence, bubbles and inclusions, homogeneity and striae). Other related parts cover surface form (‑5), centring (‑6), surface imperfections (‑7), surface texture (‑8), coatings (‑9), and aspherics (‑12).

FAQ

Q: What is this standard?

A: ISO 10110-3:1996 is a part of the ISO 10110 series that specified how to indicate permissible bubbles and inclusions on technical drawings for optical elements. It provided definitions, notation and preferred size grades for drawing callouts.

Q: What does it cover?

A: It covers presentation rules on drawings for allowable counts and maximum sizes of bubbles and inclusions (the N x A form), definitions of relevant defect types, and guidance on how such imperfections affect optical performance and inspection.

Q: Who typically uses it?

A: Lens and optical system designers, drawing authors, manufacturers, metrology/QA teams, material suppliers and procurement staff who need clear acceptance criteria for material defects.

Q: Is it current or superseded?

A: ISO 10110-3:1996 is withdrawn and its material-imperfection content (including bubbles and inclusions) has been consolidated into ISO 10110-18:2018; users should refer to the later part for the current specification.

Q: Is it part of a series?

A: Yes — ISO 10110 is a multipart series (Optics and photonics — Preparation of drawings for optical elements and systems). ISO 10110-3 was one part of that series focused on bubbles and inclusions. The series includes multiple parts for surface form, centring, surface imperfection, texture, coatings, aspherics and others.

Q: What are the key keywords?

A: Bubbles, inclusions, N x A notation, optical drawings, material imperfections, acceptance criteria, inspection, ISO 10110.
