    Abstract: Apparatus for measuring the numerical aperture of an optical fiber in the infrared region. The optical fiber (8) is appropriately mounted in accordance with conventional testing standards. Infrared energy is transmitted through the optical fiber (8). At a predetermined distance from the end of the optical fiber, a conversion screen (10) can be provided for transforming the emitted infrared energy into a lesser wavelength of energy. The energy distribution can be recorded with a detector compatible with the lesser wavelength energy whereby the numerical aperture can be computed from the recorded data.

    Abstract: Appareil pour mesurer l'ouverture numérique d'une fibre optique dans la région infrarouge. La fibre optique est montée de manière appropriée conformément aux normes d'essai classiques. On transmet de l'énergie infrarouge à travers les fibres optiques. A une distance prédéterminée de l'extrémité de la fibre optique, on peut disposer un écran de conversion pour transformer l'énergie infrarouge émise en une énergie de longueur d'onde inférieure. On peut enregistrer la distribution d'énergie à l'aide d'un détecteur compatible avec l'énergie de longueur d'onde inférieure, l'ouverture numérique pouvant être calculée à partir des données enregistrées.
