Abstract: An optical filter comprises a base material (i) which comprises a transparent resin layer comprising a compound (Z) having an absorption maximum in the wavelength region of from 600 to 850 nm; and a dielectric multilayer film provided on at least one surface of the base material (i). The optical filter selectively transmits visible rays and a part of near-infrared rays, and the optical filter satisfies specific requirements.

Abstract: An object of the present invention is to provide an optical filter having excellent visible light-cut characteristics and near-infrared rays transmission properties at a specific wavelength that are compatible with one another even in the case where the incident angle is increased, according to reduction in height of equipment on which an optical sensor device is provided. The optical filter of the present invention includes a base material (i) including a resin layer containing a compound (Z) having an absorption maximum in the wavelength region of 700 to 930 nm, and a dielectric multilayer film formed on at least one surface of the base material (i), and has specific optical properties.

Abstract: One object of the present disclosure is to show an optical filter capable of realizing both an excellent visible light transmittance and an excellent near-infrared ray-shielding performance even if an incident angle becomes large. The optical filter of the present disclosure has a base material (i) including a light absorbing layer, and transmits visible light, wherein the light absorbing layer has a maximum absorption in a wavelength range of 750 nm to 1,150 nm, and in a wavelength range of 850 nm to 1,050 nm, an average OD value measured in a direction perpendicular to the optical filter is 2.0 or more, and an average OD value measured at an angle of 60° with respect to the direction perpendicular to the optical filter is 2.0 or more.
