TS EN ISO 11145

TS EN ISO 11145 is a vocabulary standard for lasers and laser-related equipment, covering the terminology and symbols used in optics and photonics. Standards of this type do not describe how a laser must be designed or tested; instead, they create a common technical language so that engineers, manufacturers, and documentation teams use the same words and graphical conventions in the same way.

Why laser terminology needs its own standard

Laser systems combine an active optical source, resonator structures, control electronics, power supplies, optics, and often safety-related features. In that environment, names and symbols can easily become inconsistent across drawings, catalogues, manuals, and specifications. A vocabulary standard reduces ambiguity by distinguishing the equipment, its parts, and the related concepts that are routinely used in technical communication.

What this type of standard contributes in practice

• Supports consistent terminology in datasheets and technical documentation.
• Helps standardise symbols used in diagrams, labels, and related graphical documentation.
• Makes distinctions between laser equipment, components, and associated concepts easier to follow.
• Improves clarity when technical content is translated between languages.

This TSE record is based on EN ISO 11145:2016 and is withdrawn. In general, a vocabulary standard like this defines the structure of technical language rather than performance limits or mandatory test methods, so its value lies in precision, consistency, and shared understanding across the laser field.
