  • SOLID-STATE IMAGE CAPTURE ELEMENT OPTICAL FILTER AND APPLICATION THEREOF
    Publication number: 20150285971
    Abstract: An object of the present invention is to provide a solid-state image capture element optical filter having excellent visible light transmission characteristics with reduced incidence angle dependence even in the near-ultraviolet wavelength region, in which the defects of conventional optical filters such as near-infrared cut filters are improved; and a device comprising the optical filter. The solid-state image capture element optical filter of the present invention comprises: a transparent resin substrate comprising a compound (X) having an absorption maximum in a wavelength range of 300 to 420 nm and a compound (Y) having an absorption maximum in a wavelength range of 600 to 800 nm; and a near infrared-reflecting film on at least one side of the substrate.

  • OPTICAL FILTER, AND SOLID-STATE IMAGE PICKUP DEVICE AND CAMERA MODULE USING THE OPTICAL FILTER
    Publication number: 20140264202
    Abstract: The problem of the present invention is to overcome drawbacks of conventional optical filters such as near-infrared cut filters and to provide an optical filter which generates little scatted light even during light absorption and has excellent transmittance property. The optical filter of the present invention is characterized by containing a squarylium-based compound and a compound which absorbs or quenches fluorescence of the squarylium-based compound. The optical filter of the present invention preferably contains a near-infrared absorbing dye containing a squarylium compound (A) and at least one compound (B) selected from the group consisting of a phthalocyanine-based compound (B-1) and a cyanine-based compound (B-2).
