Optics and photonics - Reference wavelengths (ISO 7944:2024)
This document specifies reference wavelengths to be used for the characterization of optical materials, optical systems and instruments, and ophthalmic lenses. It defines the associated principal refractive indices and principal dispersions, as well as the Abbe numbers with regard to these reference wavelengths and principal dispersions.
Optik und Photonik - Bezugswellenlängen (ISO 7944:2024)
Dieses Dokument legt Bezugswellenlängen fest, die für die Charakterisierung von optischen Werkstoffen zu verwenden sind, optischen Systemen und Instrumenten sowie ophthalmischen Linsen. Es definiert die zugehörigen Hauptbrechzahlen und die Hauptdispersionen sowie die Abbe-Zahlen bezogen auf diese Bezugswellenlängen und die Hauptdispersionen.
Optique et photonique - Longueurs d'onde de référence (ISO 7944:2024)
Le présent document définit des longueurs d'onde de référence à utiliser pour la caractérisation des matériaux optiques, des systèmes et des instruments d'optique et des verres ophtalmiques. Il définit les indices de réfraction principaux et les dispersions principales associées, ainsi que les nombres d'Abbe par rapport à ces longueurs d'onde de référence et aux dispersions principales.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
