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

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

It is applicable to the determination of bubbles and inclusions in 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.
