摘要： In a neutral density filter, a base is formed from plastic, and a light absorbing film having a plurality of layers is disposed on at least one surface of the base. The light absorbing film includes a first layer from the base side that is a SiO2 layer or an Al2O3 layer. The light absorbing film includes one or more NiOx layers formed from NiOx (x is not less than 0 and not greater than 1). At least one of the NiOx layers is disposed between a base-side adjacent layer adjacent to the at least one of the NiOx layers on the base side, and an opposite-side adjacent layer which is formed from a material different from the base-side adjacent layer and which is adjacent to the at least one of the NiOx layers on the opposite side.

摘要： In a plastic optical product, an optical multilayer film 3 having seven layers is formed on a surface of a plastic substrate 1 directly or with an interlayer 2 interposed therebetween. In the layers of the optical multilayer film 3, a layer on the plastic substrate 1 side is a low refractive index layer, low refractive index layers and high refractive index layers are alternately disposed. At least the high refractive index layer at the center contains substoichiometric titanium oxide. In a plastic lens for spectacles belonging to such a plastic optical product, the plastic substrate 1 is a plastic lens substrate for spectacles, the interlayer 2 is a hard coat film, and the optical multilayer film 3 is an anti-reflective film.

摘要： A spectacle lens includes an optical multilayer film formed on at least one surface of a base. The spectacle lens is formed such that, in a reflectance distribution in a visible region, maximal values appear in a range of wavelengths that are not less than 440 nm and not greater than 460 nm and in a range of wavelengths that are not less than 620 nm and not greater than 640 nm. A blue light ray cutting rate calculated by using a calculation formula described in Japanese Industrial Standards “JIS T7333 Appendix C” is not less than 7% (preferably not less than 8%) in the spectacle lens. A YI value is not greater than 6 in the spectacle lens.

摘要： The optical product includes an optical multilayer film which is disposed on one surface or both surfaces of a base directly or via an intermediate film. The optical multilayer film is obtained by alternately disposing an SiO2 layer and a ZrO2 layer, forming nine layers in total, such that a first layer counting from the base is the SiO2 layer. The optical thickness of the SiO2 layer as the first layer is not greater than 0.120×λ/4 when a design wavelength is λ (500 nm), the optical thickness of the ZrO2 layer as a second layer is not less than 0.400×λ/4, the optical thickness of the SiO2 layer as a third layer is not less than 0.230×λ/4, and the optical thickness of the SiO2 layer as a seventh layer is not less than 0.450×λ/4.
