Title:
二色性偏光子及び材料
Document Type and Number:
Japanese Patent JP4163414
Kind Code:
B2
Abstract:
The invention pertains to thermo-resistant and light-resistant dichroic polarizers based on thin films of dichroic matters, in particular organic dyestuffs, in which molecules are ordered in a crystalline structure and applied on the surface of the substrate. The dichroic polarizer is characterized by the fact that it contains at least one anisotropically absorbing film comprised of oriented molecules. Anisotropically absorbing film is characterized by the fact that for the major axes of the ellipsoids of the real and imaginary parts of anisotropic refraction coefficient in the range of at least one absorption band of the following is true on the area with linear dimensions no less than the maximum wavelength: K1>=K2>K3 ( n 1 + n 2 ) 2 > n 3 where K1, K2, K3 and n1, n2, n3, are main values of the semiaxes of the ellipsoid representing the imaginary and real parts, accordingly, of the anisotropic refraction coefficient, and/or the anisotropically absorbing film is characterized by the fact that light transmission by two films with cross-oriented polarization axes does not increase at least in some range of wavelengths upon the deviation of its propagation from the normal to the polarizer plane.
