NIR Wire Grid Polarizer, HC, 700-2500nm, 50mm Dia.

Product Details Designed for 700 – 2500nm High Transmission and High Contrast Versions Available Ideal for Thermal Imaging NIR Wire Grid Polarizers are broadband polarizers designed to provide high transmission from 700 – 2500nm. These polarizers are optimized as either a high contrast version, providing 5900:1 extinction ratio at 2400nm, or as a high transmission version providing up to 91% transmission at 1900nm. NIR Wire Grid Polarizers are manufactured on high-grade display glass, providing excellent heat resistance for NIR applications. When incident light strikes the wire grid, P-polarized light contacts a dielectric and is transmitted, while S-polarized light contacts a mirror and is reflected.
