Abstract: An optical multilayer film of a light-shielding member includes light absorbing layers that absorb visible light and dielectric layers that are made of a dielectric such that a total number of the layers is 4 or more. A surface-side light absorption thickness which is a total of physical film thicknesses of the light absorbing layers disposed between the outermost layer and a next outermost layer is not less than 6 nm and not greater than 17 nm. A base-side light absorption thickness which is a total of physical film thicknesses of the light absorbing layers disposed between the next outermost layer and the base is not less than 60 nm. A specific proportion, regarding a specific surface layer thickness which is a total of the physical film thicknesses of layers from a base-side maximum-thickness light absorbing layer to the outermost layer, is not less than 0.34.

Abstract: In the optical product bending prediction method according to the present invention, bending ? of a substrate having a film is predicted by a computer performing calculation (steps S11 to S13) of the following Expressions (A1), (B1), etc., in which a and Td are set as fitting parameters and have been optimized in each coating condition using a plurality of samples. Here, ?int is intrinsic stress, Ef is a Young's modulus of a multilayer film, vf is a Poisson's ratio of the multilayer film, ?f is a linear coefficient expansion of the multilayer film, ?s is a linear coefficient expansion of the substrate, T is a room temperature, d is a film thickness, b is a substrate thickness, l is a radius of the substrate, Es is a Young's modulus of the substrate, and vs is a Poisson's ratio of the substrate.

Abstract: An optical product is provided with an optical multilayer film formed on one or both of surfaces of a base, directly or via an intermediate film. The optical multilayer film is obtained by alternately layering low refractive index layers and high refractive index layers up to five layers or more in total. The high refractive index layers include zirconium dioxide layers each having an atmospheric refractive index not less than 2.11 with respect to light having a wavelength of 500 nanometers. The total of physical thicknesses of the zirconium dioxide layers each having the atmospheric refractive index not less than 2.11 is not less than 20% of the total physical thickness of the optical multilayer film.
