Full title and description

St ISO 15902-2019 — Optics and photonics — Diffractive optics — Vocabulary. This International Standard (Edition 2, 2019) defines basic terms and agreed common terminology for diffractive optical elements and related concepts used in free-space propagation, to reduce ambiguity and support development and communication in the field of diffractive optics.

Abstract

The standard provides definitions of the basic terms for diffractive optical elements (DOEs) for free-space propagation. Its purpose is to establish a common vocabulary that reduces ambiguity and misunderstanding and thereby aids development and application of diffractive optics.

General information

• Status: Published (International Standard, confirmed stage).
• Publication date: December 2019 (Edition 2, published 2019-12).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 31.260 (Optics and photonics); 01.040.31 (Terminology and documentation for electronics/laser).
• Edition / version: Edition 2 (2019).
• Number of pages: 14 (official ISO paginated length for the 2019 edition).

Scope

Applies to vocabulary and basic terminology for diffractive optical elements used in free-space propagation. The document is intended for use by designers, manufacturers, researchers and standards developers to provide uniform definitions for terms related to diffractive optics so that specifications, drawings and technical communications are consistent and unambiguous. (The 2019 edition replaces the earlier 2004 edition/corrigendum.)

Key topics and requirements

• Standardized definitions for core diffractive-optics terms (diffractive optical element, diffraction order, diffraction efficiency, grating, phase profile, kinoform, Fresnel zone plate, etc.).
• Terminology to describe geometry and functional characteristics of DOEs for free-space propagation (surface relief vs. phase-only elements, groove/feature descriptions, blaze, etc.).
• Common symbols and descriptors to improve clarity in specifications, drawings and technical reports involving diffractive surfaces.
• Replacement of the 2004 edition and its corrigendum with updated or clarified wording where appropriate.

Typical use and users

Used by optical engineers, optical designers, researchers in photonics, manufacturers of diffractive optical elements, metrology and quality teams, standards committees and educators who need consistent terminology when specifying, designing, manufacturing or testing DOEs and diffractive surfaces.

Related standards

Standards produced by ISO/TC 172 (Optics and photonics) and its subcommittees are closely related. Notable related documents include ISO 14880‑1 (Microlens arrays — Vocabulary) and parts of the ISO 10110 series dealing with preparation of drawings and diffractive surfaces (for example ISO 10110‑16:2023 on diffractive surfaces). These provide complementary vocabulary and drawing/description rules for optical elements and diffractive surfaces.

FAQ

Q: What is this standard?

A: ISO 15902:2019 is an International Standard titled "Optics and photonics — Diffractive optics — Vocabulary" that defines agreed terms and basic vocabulary for diffractive optical elements (Edition 2, 2019).

Q: What does it cover?

A: It covers definitions and standardized terminology for diffractive optical elements used in free-space propagation, helping to ensure consistent use of terms in specifications, drawings and technical communications.

Q: Who typically uses it?

A: Optical engineers, designers and manufacturers of diffractive elements, researchers in photonics, metrology and quality assurance teams, and standards committees use it to harmonize vocabulary.

Q: Is it current or superseded?
