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.
