Controlled bleaching of the iodine dichromophore from iodine-polyvinyl alcohol polarizers has been demonstrated to result in a dramatic increase in transmission. Internal transmission of 95% for linearly polarized light has been observed in the spectral range of 5000–6000 Å. Degradation of polarizer extinction is most severe at shorter wavelengths; however, the transmittance for the crossed polarization remains <0.1% through much of the visible spectrum.
