纳米颗粒线偏振片通过在玻璃中植入细长形的纳米银颗粒产生偏振，纳米尺度金属粒子对光波的选择性吸收和散射特性来实现偏振效果，银纳米颗粒会吸收和反射垂直于透射轴的偏振光，和银颗粒垂直的偏振光将会透过。相比于传统的分子聚合物线偏振片，纳米颗粒线偏振片有更显著的优势，它具有更高的损伤阈值和更高的消光比。

Nanoparticle Linear Polarizer is comprised from silver particles that have been embedded in sodium-silicate glass, silver particles absorb incident radiation, thereby non-polarized light will be polarized linear and already polarized light is blocked or allowed to pass depending on orientation. Nanoparticle Linear Polarizer offer better performance than conventional polymer-based linear polarizers. Nanoparticle Linear Polarizer has a significantly higher damage threshold and better extinction ratio than polymer-based polarizer. The transmission axis is marked by two dots at the edge of the polarizer
