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. NOTE Additional information on how to translate optical element specifications into raw optical glass specifications is given in Annex A.
