摘要: A lens includes a lens unit; an anti-reflective (AR) coating layer, disposed on one surface of the lens unit, including a first coating layer and a second coating layer alternately stacked one or more times, wherein a refractive index of the first coating layer is different from a refractive index of the second coating layer; and an intermediate layer, disposed between the lens unit and the AR coating layer, is formed of a same material as the first coating layer or the second coating layer. The intermediate layer is disposed on the lens unit by chemical vapor deposition (CVD).
