  • Optical filter and optical sensor device
    Patent number: 11163098
    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.
    Type: Grant
