BS ISO 19741:2018

This standard BS ISO 19741:2018 Optics and photonics. Optical materials and components. Test method for striae in 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 striae in infrared optical materials.

It is applicable to 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.
