The 10LP-NIR Precision Linear Polarizers is constructed by laminating a polymer polarizing film between two high-precision glass or fused silica windows. Each window has a high-efficiency 1100 to 1750 nm broadband NIR antireflection coating. The assembly is mounted in a 1 inch (25.4 mm) diameter black anodized aluminum housing for protection and provides a 17.8 mm clear aperture. The transmission axis is clearly marked. The result is a linear polarizer with high transmission and low wavefront distortion that are easy to mount.

10LP-NIR精密线性偏振器是将聚合物极化膜在两个高精度玻璃或熔融二氧化硅窗口之间叠层而成。每个窗口都有一个高效的1100至1750纳米宽带近红外防反射涂层。该总成安装在直径1英寸(25.4 mm)的黑色阳极氧化铝外壳中，用于保护，并提供17.8 mm的透明孔径。传动轴标记清楚。结果是一种高透射、低波前畸变、易于安装的线性偏振器。
