Optics and photonics — Effective numerical aperture of laser lenses — Definition and verification procedure

Optique et photonique — Ouverture numérique efficace des lentilles laser — Définition et procédure de vérification

Abstract / scope

This document covers terms, definitions, and a verification procedure to characterize the ability of laser lenses to collimate divergent laser beams and to focus collimated laser to small spot sizes. The aim of this document is to give users reliable information on the applicability of laser lenses in the field of beam forming.
