Optique et photonique — Matériaux et composants optiques — Méthodes d’essai pour déterminer les stries des matériaux optiques infrarouges

This document specifies the principle, apparatus, condition, sample, procedure and data processing of measuring striae in infrared optical materials.

It is applicable for the determination of striae in infrared optical materials, such as infrared optical glass, which is opaque to visible wavelengths and whose transmission optical spectra are beyond 0,78 µm.
