Abstract
An antireflection film is arranged on a surface of a substrate layer. The antireflection film includes a multilayer film arranged on the surface of the substrate layer and a protective film arranged outside the multilayer film. The multilayer film is formed by stacking two or three low-reflection layers. Two protective films are successively arranged outside the multilayer film of the antireflection film. An optical component includes the antireflection film arranged on both sides or one side of an optical filter of the optical component. The high-performance antireflection film can be obtained with respect to a broadband wavelength ranging from 400 nm to 800 nm, and the antireflection film can reduce the occurrence of ghosts or flare when used in an optical system.
