BK7和 UV FS材质的薄膜激光偏振器（TFP）有大量型号可选，并且能快速供货。这类薄膜偏振器具备极高的激光损伤阈值，专为最严苛的使用场景而设计，既适用于工作波段在1040–1070nm的Nd基激光器，也适配飞秒级别的钛宝石或掺镱（Yb:KGW/KYW）激光器。所谓56度薄膜偏振器，也常被称为薄膜偏光片、偏振分光镜或薄膜偏振片TFP。
激光薄膜偏振片TFP分离特定波长或波长范围的s偏振和p偏振分量。由于激光薄膜偏振片TFP在1064nm处达到10J/cm2的高损伤阈值，10ns薄膜偏振器在高能激光器的应用中取代了Glan激光偏振棱镜或立方体偏振分束器。

薄膜偏光片用于高能激光器。激光薄膜偏振片TFP可用于Yb:KGW/KYW或Ti:Sapphire激光器的基波波长及其谐波，或是用作腔内Q开关保持偏振器。使用薄膜激光偏振器的最有效方法是在布儒斯特角-56°±2°，损耗最小。
我们提供四种类型的薄膜偏振器：
标准-Rs/Tp:>99.5/95.0%，消光比Tp/Ts>200:1
高透射率（HT）-Rs/Tp:>99.5/99.0%，消光比Tp/Ts>200:1
超高透射率（UHT）-Ts<0.2%，Rp<0.2%，消光比Tp/Ts>200:1
高消光比（HE）-Tp>98%，Ts<0.1%，消光比Tp/Ts>1000:1
