Polarcor Linear Polarizer, 12.7 mm, 8.1 mm Clear, 94%, 1270-1340 nm
The 05P409AR.18 Polarcor™ Linear Polarizer is a 1/2 inch (12.7 mm) diameter linear polarizer with an 8.1 mm clear aperture offering 94% principle transmission in the 1270 to 1340 nm wavelength range. It features broader bandwidth, higher transmission, higher temperature resistance, better durability, and higher contrast than dichroic sheet or wire grid polarizers. All Polarcor polarizers are broadband antireflection coated to increase transmission of polarized light.
