Lasers and laser-related equipment - Test methods for laser beam widths, divergence angles and beam propagation ratios - Part 1: Stigmatic and simple astigmatic beams (ISO 11146-1:2021)

This document specifies methods for measuring beam widths (diameter), divergence angles and beam propagation ratios of laser beams. This document is only applicable for stigmatic and simple astigmatic beams. If the type of the beam is unknown, and for general astigmatic beams, ISO 11146‑2 is applicable.

Laser und Laseranlagen - Prüfverfahren für Laserstrahlabmessungen, Divergenzwinkel und Beugungsmaßzahlen - Teil 1: Stigmatische und einfach astigmatische Strahlen (ISO 11146-1:2021)

Dieses Dokument legt Verfahren zur Messung von Strahlabmessungen (Strahldurchmesser), Divergenz-winkeln und Beugungsmaßzahlen von Laserstrahlen fest. Dieses Dokument ist nur für stigmatische und einfach astigmatische Strahlen anzuwenden. Wenn die Art des Strahles unbekannt ist und bei allgemein astigmatischen Strahlen, ist ISO 11146 2 anzuwenden.

Lasers et équipements associés aux lasers - Méthodes d'essai des largeurs du faisceau, angles de divergence et facteurs de limite de diffraction - Partie 1: Faisceaux stigmatiques et astigmatiques simples (ISO 11146-1:2021)

Le présent document spécifie les méthodes pour mesurer les largeurs (diamètres) du faisceau, les angles de divergence et les facteurs de limite de diffraction. Le présent document s'applique uniquement aux faisceaux stigmatiques et astigmatiques simples. Si le type de faisceau est inconnu et pour les faisceaux astigmatiques généraux, l'ISO 11146‑2 s'applique.
