Abstract

Long-term testing of silicate and borate optical glasses is performed in a humid environment. Products of water reacting with glass components are shown to form on the borate glass surface, causing an increase in the roughness parameter R z. Pretreatment in hexamethyldisiloxane vapors reliably protects glasses from aggressive moisture. Silicate optical glasses are more resistant to humidity and do not require pretreatment. Roughness parameter R z is found to be an inadequate metric of the roughness of the surface with a protective coating, owing to the limitations of its determination. Topographic measurements are more reliable in this instance.
