摘要:
A catadioptric optical membrane, which is disposed on a surface of a substrate, includes a reflection membrane and a matting membrane. The reflection membrane is disposed on an effective optical path area of the substrate and includes a reflection metal membrane and a reflection oxidation membrane. The reflection oxidation membrane includes a first reflection oxidation membrane and a second reflection oxidation membrane. The reflection metal membrane is farther away from the substrate than the first reflection oxidation membrane. The second reflection oxidation membrane is farther away from the substrate than the reflection metal membrane. The matting membrane is disposed on a non-effective optical path area of the substrate. The matting membrane includes a deep-color membrane and a first anti-reflection membrane. The deep-color membrane includes a deep-color metal membrane and a deep-color oxidation membrane. The deep-color membrane is farther away from the substrate than the first anti-reflection membrane.
