NIR Linear Polarizers, 25.0 mm Dia., 2.0 mm thick, 750-850 nm

Unmounted Laminated Polymer Film Linear Polarizers

The LPNIR-1 NIR Linear Polarizer has a 25.0 mm diameter and is 2.0 mm thick. It is constructed by laminating a polymer polarizing film between two high-precision glass windows. The transmission on a single filter is about 30% from 750 to 850 nm.
