An optical component with improved degradation resistance is provided. The optical component includes an optical material and a coating. The optical material has a native surface that is susceptible to degradation processes. The coating is a layer of an inorganic material and is applied so as to be substantially contiguous so that there are no continuous paths between fluid surrounding the optical component and the optical material.
