BVO NIR Diode Polarizer
The near infrared polarizer that made LED light bank polarization possible. By far the lowest cost NIR linear polarizer on the market making large format polarization possible. The NIR diode linear polarizer is especially useful for solid state sensors because internal scatter does not impact performance.
