    摘要： A reflective polarizer and a dichroic polarizer are combined to provide an improved optical polarizer. The dichroic and reflective polarizers are typically in close proximity to each other, and are preferably bonded together to eliminate the air gap between the polarizers. The combination of the two polarizers provides a high reflectivity of one polarization and high transmission for the perpendicular polarization from the reflective polarizer side of the combined polarizer, and high absorption and transmission for light of orthogonal polarization from the dichroic polarizer side. The combination also reduces iridescence as seen in transmission and when viewed in reflection from the dichroic polarizer side. The increased extinction ratio and low reflectivity of the optical polarizer allows use of a lower extinction ratio dichroic polarizer in applications requiring a given extinction ratio and high transmission.

    摘要翻译： 将反射偏振器和二向色偏振器组合以提供改进的光学偏振器。 二向色和反射偏振器通常彼此靠近，并且优选地结合在一起以消除偏振器之间的气隙。 两个偏振器的组合为来自组合偏振器的反射偏振器侧的垂直偏振提供一个偏振和高透射率的高反射率，以及来自二向色偏振器侧的正交偏振光的高吸收和透射。 该组合还减少透射中看到的虹彩，并且当从二向色偏振器侧反射时观察。 光学偏振器的消光比和低反射率的增加允许在需要给定消光比和高透射率的应用中使用较低消光比的二向色偏振器。
