摘要： The optical element includes a base member configured to have an optical surface, a concave-convex structure configured to have an average pitch smaller than a shortest wavelength of a use wavelength range, and an intermediate layer formed between the optical surface and the concave-convex structure, made of a material different from that of the concave-convex structure, and having a refractive index between those of the base member and the material of the concave-convex structure. The optical surface is formed into a shape having a rotational symmetry axis. A thickness of the intermediate layer or each of thicknesses of the intermediate layer and the concave-convex structure varies so as to increase as a distance from the rotational symmetry axis increases. The optical element has good anti-reflection performance not only at a central part of the optical surface having a small curvature radius but also at a peripheral part thereof.

摘要： An optical element includes a substrate, and an antireflection film provided on a surface of the substrate. The antireflection film is a graded layer having a refractive index that is progressively decreased from the substrate side towards an outer surface of the antireflection film. The graded layer has a reflectivity characteristic occupying ⅔ of a usable wavelength range around the center of the usable wavelength range. Reflectivity of the graded layer at a maximum value of the reflectivity characteristic is a peak value equal to or less than 0.4% The graded layer does not have a maximal value not corresponding to the peak value. At least one of reflectivities at both ends of the usable wavelength range is equal to or less than half the reflectivity at the peak value.
