Title:
OPTICAL MULTILAYERED FILTER
Document Type and Number:
Japanese Patent JP3290629
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide optical multilayered filters having good optical characteristics without interference and the optical multilayered filters having high productivity.
SOLUTION: The optical multilayered filters formed by laminating dielectric thin films to multiple layers in a single direction are composed to have refractive index inclining lamination parts C where the refractive index of the dielectric thin film layers change successively incline and change in the lamination direction and alternate lamination parts A where the dielectric thin film layers of a high refractive index and the dielectric thin film layers of a low refractive index are alternately laminated. The color filters are composed by forming a plurality of the inclining lamination parts C and the alternate lamination parts A so as to hold these parts in the lamination direction.
