Optical member, method for producing the same, and optical system

摘要

An optical member includes a glass base (1) and plural layers formed on a surface of the glass base. The plural layers include at least one plate-crystal layer (3) having a textured structure (4) formed by plate crystals comprising mainly aluminum oxide, and at least one polymer layer (2) formed between the base and the at least one plate-crystal layer and comprising mainly a polymer having an organosilsesquioxane structure. The at least one polymer layer may be a layer obtained by curing an organosilsesquioxane oligomer and/or polymer.
