A method of hygroscopic optical material fabrication comprising the steps of cutting a hygroscopic optical material to generate an optical substrate of appropriate dimensions and polishing the hygroscopic optical material for appropriate surface figure or surface quality. The cutting and polishing of the hygroscopic optical material is completed while the hygroscopic optical material is isolated from aqueous contamination so as to maintain or increase the damage threshold of the hygroscopic optical material.
