ISO 12123-2018 光学和光子学--未加工的光学玻璃规范 Optics and photonics -- Specification of raw optical glass

This document gives rules for the specification of raw optical glass. It serves as a complement to the 
ISO 10110 series, which provides rules specifying finished optical elements. Since raw optical glass can 
be quite different in shape and size from the optical elements, its specification also differs from that of 
optical elements.
This document provides guidelines for the essential specification characteristics of raw optical glass 
in order to improve communication between glass suppliers and optical element manufacturers. For 
specific applications (e.g. lasers, the infrared spectral range), specifications based on this document 
need supplements.
While the intent of this document is to address the specific needs of raw optical glass, many of the 
parameters and characteristics are common to other optical materials, which are not necessarily glass. 
While this document can be used for non-glass materials, the user is informed that only optical glass 
has been considered in the development of this document, and other materials can have issues, which 
have not been taken into consideration.
