薄膜偏振器可以分离266nm~1570nms偏振和p偏振分量，消光比Tp/Ts>200:1和Tp/Ts>1000:1。激光薄膜偏振片TFP有四种类型，分别是标准Rs/Tp:>99.5/95.0%、高透射率Rs/Tp:>99.5/99.0%、超高透射率Ts<0.2%Rp<0.2%和高消光比Tp>98%，Ts<0.1%四种。Eksma薄膜激光偏振器入射角度56°，所以又可以叫作56度薄膜偏振器和偏振分光镜，薄膜偏光片镜片形状有圆形和矩形。

薄膜偏振器56°入射，266-1570nm，消光比Tp/Ts>200:1、>1000:1
BK7和UV FS薄膜激光偏振器（TFP）种类繁多，可快速交付。薄膜偏振器具有高激光损伤阈值，专为要求最苛刻的应用而设计，适用于Nd基激光器在1040-1070 nm范围内的运行，以及飞秒级Ti:Sapphire或Yb:KGW/KYW激光器。56度薄膜偏振器又可以叫作薄膜偏光片、偏振分光镜和薄膜偏振片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
