Optics and optical instruments - Test lenses for calibration of focimeters - Part 1: Reference lenses for focimeters used for measuring spectacle lenses (ISO 9342-1:2023)

This document specifies requirements for reference lenses for the calibration and verification of focimeters that are used for the measurement of spectacle form lenses, e.g. those complying with ISO 8598-1. It also gives a method for the determination of the back vertex power of the reference lenses.
NOTE            It is accepted that other reference lenses can also be used with powers within the given range, manufactured to the same standard of accuracy and form, but different back vertex powers. However, only lenses with integer nominal powers, as described in 4.1, can be used for the calibration of digitally-rounding focimeters.

Optik und optische Instrumente - Prüfgläser zur Kalibrierung von Scheitelbrechwert-Messgeräten - Teil 1: Referenzgläser für Scheitelbrechwert-Messgeräte für die Messung von Brillengläsern (ISO 9342-1:2023)

Dieses Dokument legt Anforderungen an Referenzgläser zur Kalibrierung und Überprüfung von Scheitelbrechwert-Messgeräten fest, die für die Messung von Brillengläsern verwendet werden, z. B. solche, die der ISO 8598 1 entsprechen. Es enthält auch ein Verfahren zur Bestimmung des bildseitigen Scheitelbrechwerts der Referenzgläser.
ANMERKUNG   Die Verwendung anderer Referenzgläser, deren Brechwert im angegebenen Bereich liegt und die bezüglich Genauigkeit und Form gleichwertig gefertigt wurden, jedoch andere bildseitige Scheitelbrechwerte aufweisen, ist ebenfalls zulässig. Für die Kalibrierung von digital rundenden Scheitelbrechwert-Messgeräten können jedoch nur Gläser mit einem ganzzahligen Sollscheitelbrechwert, wie in 4.1 beschrieben, verwendet werden.

Optique et instruments d'optique - Verres étalons pour l'étalonnage des frontofocomètres - Partie 1: Verres de référence pour frontofocomètres pour le mesurage des verres de lunettes (ISO 9342-1:2023)

Le présent document spécifie les exigences applicables aux verres de référence pour l'étalonnage et la vérification des frontofocomètres utilisés pour le mesurage des verres de lunettes, par exemple ceux qui sont conformes à l'ISO 8598-1. Il donne en outre une méthode qui permet de déterminer la puissance frontale arrière des verres de référence.
NOTE            Il est admis que d'autres verres de référence ayant des puissances situées dans la plage donnée, fabriqués selon les mêmes normes d'exactitude et de courbure, mais ayant des puissances frontales arrière différentes, puissent être utilisés. Cependant, pour l'étalonnage des frontofocomètres à affichage numérique avec arrondi, on ne peut utiliser que des verres ayant des puissances nominales entières, comme décrit en 4.1.

Optika in optični instrumenti - Preskusne leče za umerjanje fokometrov – 1. del: Referenčne leče za fokometre, ki se uporabljajo za merjenje spektralnih leč (ISO 9342-1:2023)

Ta dokument določa zahteve za referenčne leče za umerjanje in preverjanje fokometrov, ki se uporabljajo za merjenje spektralnih leč, npr. tistih, ki so skladne s standardom ISO 8598-1. Prav tako podaja metodo za določanje moči referenčnih leč glede na vrh na zadnji strani.
OPOMBA: Sprejemljivo je, da se lahko uporabljajo tudi druge referenčne leče z močmi znotraj danega območja, ki so izdelane po enakem standardu natančnosti in oblike, vendar z različnimi močmi glede na vrh na zadnji strani. Vendar pa se lahko za umerjanje fokometrov z digitalnim zaokroževanjem uporabljajo le leče s celimi nazivnimi močmi, kot je opisano v točki 4.1.
