BS EN ISO 11145:2026

This standard BS EN ISO 11145:2026 Optics and photonics. Lasers and laser-related equipment. Vocabulary and symbols is classified in these ICS categories:

• 11.040.99 Other medical equipment
• 01.040.31 Electronics (Vocabularies)
• 31.260 Optoelectronics. Laser equipment
• 01.080.40 Graphical symbols for use on electrical and electronics engineering drawings, diagrams, charts and in relevant technical product documentation

This document defines basic terms, symbols and units of measurement for the field of laser technology in order to unify the terminology, and to arrive at clear definitions and reproducible tests of beam parameters and laser-oriented product properties. NOTE            The laser hierarchical vocabulary laid down in this document differs from that given in IEC 60825–1. ISO and IEC have discussed this difference and agree that it reflects the different purposes for which the two standards serve. For more details, see informative Annex A.
