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

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

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