unmounted precision linear polarizer model lpgf-2

Overview

The LPGF and LPNIR series linear polarizers are not mounted in a housing for a lower cost option. They are constructed by laminating a polymer polarizing film between two high-precision glass windows. They are available in 400-700 nm, 750-850 nm and 1000-2000 nm wavelength ranges. These high contrast polarizers are ideal for a wide range of applications involving low power NIR lasers, LEDs, and other NIR sources.
