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.

摘要： An optical imaging lens assembly includes at least one optical lens element. The optical lens element includes an anti-reflective coating, and the anti-reflective coating is arranged on at least one surface of the optical lens element. The anti-reflective coating includes a high-low refractive coating and a gradient refractive coating, and the high-low refractive coating is arranged between the optical lens element and the gradient refractive coating. The high-low refractive coating includes at least one high refractive coating layer and at least one low refractive coating layer, which are stacked in alternations. The low refractive coating layer is in contact with the optical lens element. The gradient refractive coating includes a plurality of holes, and the holes away from the optical lens element are relatively larger than the holes close to the optical lens element.
