Abstract:
A light filtering element, includes: at least one layer, a first layer of the at least one layer being stretched along a strain direction and including a first narrowband dye, the first narrowband dye including a first narrowband dye peak absorbance wavelength with a first narrowband dye bandwidth; and a first dichroic dye configured to absorb polarized light, the first dichroic dye including a first dichroic dye peak absorbance wavelength with a first dichroic dye bandwidth, molecules of the first dichroic dye being at least partially oriented along the strain direction.
