Optics and photonics — Optical materials and components — Test method for striae in infrared optical materials Published (Edition 2, 2025)

Abstract

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.
