Near infrared ray absorbing filter

摘要: PROBLEM TO BE SOLVED: To provide a near infrared ray absorbing filter which can attain thickness reduction and has high transmittance in visible region. SOLUTION: The transparent substrate 1, an organic film layer 2 is formed on one side or both sides of the 1 absorbs rays inorganic layers 3,4 for intercepting rays. made to have ≥90% region 20% 60% consisting polymer composition containing at least kind dyestuff. comprise multilayer constituted by alternatively laminating dielectric low refractive index index. By combining dyestuff comprising optical film, attained high. COPYRIGHT: (C)2008,JPO&INPIT
