NF EN ISO 11551

Optics and photonics — Lasers and laser-related equipment — Test method for absorptance of optical laser components

Le présent document spécifie les modes opératoires et les techniques utilisés pour obtenir des valeurs comparables du facteur d''absorption des composants optiques pour lasers. Il spécifie la préparation de l''échantillon d''essai et du dispositif de mesurage ainsi que les éléments caractéristiques du faisceau laser. Il détaille les modes opératoires d''étalonnage du signal de puissance, de température, de la réponse thermique et du mesurage du bruit de fond. Les phénomènes modifiant le facteur d''absorption, l''influence des distorsions du signal et l''algorithme de paramétrisation des données de température sont donnés dans des annexes respectives.

To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.

With Requirements, quickly access the main part of the normative text!

The Redline + service - standards comparator allows you to easily and simply identify major changes between the current standard and its last canceled version.

At a glance, you will be able to identify the additions, deletions or modifications to a text, table, figure and formula.


The Redlines + service is offered to you on the collection of French standards in force, in French language and in HTML and PDF format.
