The optical film includes a first, a second and a third dielectric multilayer films, in the respective multilayer films a plurality of dielectric layers having different refractive indexes being laminated. The first dielectric multilayer film has a first light transmission range within a wavelength of visible light. The second dielectric multilayer film has a second light transmission range falling within the first light transmission range and has an average refractive index higher than that of the first dielectric multilayer film. The third dielectric multilayer film blocks light having twice a wavelength of a central wavelength of the second light transmission range. The second dielectric multilayer film is disposed, together with the first dielectric multilayer film or the third dielectric multilayer film, on a same main surface side of the base."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optical filter member and imaging device provided with the same","description":"An optical filter member includes a transparent base; and an optical film disposed on a surface of the base.
