TS EN ISO 15902

TS EN ISO 15902 is a terminology standard for diffractive optics, defining the basic terms and definitions used in this field. It establishes a common vocabulary for diffractive optical elements used in free-space propagation, helping engineers, researchers, and manufacturers use the same concepts with the same meaning.

How diffractive optics is framed conceptually

Diffractive optics uses diffraction to steer, focus, split, or shape light through structured optical features rather than through purely refractive or reflective behavior. In general technical context, this makes the field closely tied to microstructured surfaces, phase control, and beam shaping concepts. The purpose of this standard is to align the terminology around those ideas so that the same device or function is not described inconsistently across papers, specifications, and product information.

What the shared vocabulary supports

• It organises the basic naming used for diffractive optical elements in free-space propagation.
• It reduces ambiguity and misunderstanding in technical communication.
• It provides a common reference point for development work in diffractive optics.
• It helps distinguish between related optical components and functions more clearly.

This document is not a design handbook or a performance specification; its role is to define terms. That makes it especially useful where precise language matters, such as R&D documentation, product descriptions, procurement text, and technical reporting. Within optics and photonics, consistent terminology is essential for separating diffraction-based approaches from other optical mechanisms and for describing devices and functions in a way that supports clear professional communication.
