BS ISO 19740:2018

This standard BS ISO 19740:2018 Optics and photonics. Optical materials and components. Test method for homogeneity of infrared optical materials is classified in these ICS categories:

• 37.020 Optical equipment

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.
