Zusammenfassung: | An optical member includes a transparent substrate, an alumina-based first transparent ceramic layer on the transparent substrate, and an alumina-based second transparent ceramic layer on the alumina-based first transparent ceramic layer such that the alumina-based first transparent ceramic layer is between the transparent substrate and the alumina-based second transparent ceramic layer. A refractive index of the alumina-based second transparent ceramic layer is smaller than a refractive index of the alumina-based first transparent ceramic layer. The alumina-based first transparent ceramic layer and the alumina-based second transparent ceramic layer may have independent compositions, and the independent compositions may each be a silica-free composition. |
