Optics and photonics - Test method for total scattering by optical components (ISO 13696:2022)
This document specifies procedures for the determination of the total scattering by coated and uncoated optical surfaces. Procedures are given for measuring the contributions of the forward scattering or backward scattering to the total scattering of an optical component.
This document applies to coated and uncoated optical components with optical surfaces that have a radius of curvature of more than 10 m. Measurement wavelengths covered by this document range from the ultraviolet above 250 nm to the infrared spectral region below 15 µm. For measurements in the deep ultraviolet between 190 nm to 250 nm, specific methods are considered and are described. Generally, optical scattering is considered as neglectable for wavelengths above 15 µm.
Optik und Photonik - Bestimmung von totaler Streustrahlung, hervorgerufen durch optische Komponenten (ISO 13696:2022)
Dieses Dokument legt ein Prüfverfahren für die Bestimmung der totalen Streuung von beschichteten und unbeschichteten optischen Oberflächen fest. Verfahren zur Messung der Beiträge der Vorwärts- oder Rückwärtsstreuung zur Gesamtstreuung von optischen Komponenten werden angegeben.
Dieses Dokument bezieht sich auf beschichtete und unbeschichtete optische Komponenten mit optischen Oberflächen, die einen Krümmungsradius von mehr als 10 m besitzen. Die von diesem Dokument abgedeck¬ten Messwellenlängenbereiche reichen vom Ultraviolettbereich oberhalb von 250 nm bis in den infraroten Spektralbereich unterhalb von 15 µm. Für Messungen im tiefen Ultraviolettbereich zwischen 190 nm und 250 nm werden spezifische Verfahren in Betracht gezogen, die in diesem Dokument beschrieben sind. In der Regel kann die optische Streuung für Wellenlängen oberhalb 15 µm als vernachlässigbar betrachtet werden.
Optique et photonique - Méthodes d’essai du rayonnement diffusé par les composants optiques (ISO 13696:2022)
Le présent document définit les méthodes de détermination de la diffusion totale par des surfaces optiques revêtues et non revêtues. Des procédures sont indiquées pour mesurer les contributions de la prodiffusion ou de la rétrodiffusion à la diffusion totale d'un composant optique.
Le présent document s'applique aux composants optiques revêtus et non revêtus dont les surfaces optiques ont un rayon de courbure supérieur à 10 m. Les mesures de longueurs d'onde couvertes par le présent document vont de l'ultraviolet au-dessus de 250 nm à la région spectrale infrarouge en dessous de 15 µm. Pour les mesures dans l'ultraviolet profond entre 190 nm et 250 nm, des méthodes spécifiques sont envisagées et sont décrites. En général, la diffusion optique est considérée comme négligeable pour les longueurs d'onde supérieures à 15 µm.
Optika in optični instrumenti - Preskusne metode za sevanje, razpršeno z optičnimi komponentami (ISO 13696:2022)
Ta dokument določa postopke za ugotavljanje skupnega sevanja, razpršenega s prevlečenimi in neprevlečenimi optičnimi površinami. Podaja postopke za merjenje prispevkov razpršenega sevanja v smeri naprej ali nazaj k skupnemu razpršenemu sevanju optične komponente.
Ta dokument se uporablja za prevlečene in neprevlečene optične komponente z optičnimi površinami, katerih polmer ukrivljenosti znaša več kot 10 m. Valovne dolžine meritev, zajete v tem dokumentu, segajo od ultravijoličnega območja nad 250 nm do infrardečega spektralnega območja pod 15 µm. Za meritve v kratkovalovnem ultravijoličnem območju spektra med 190 nm in 250 nm so obravnavane in opisane posebne metode.
Na splošno velja, da je pri valovnih dolžinah nad 15 µm optično razpršeno sevanje zanemarljivo.

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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
