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.
A Diffuse Reflective Linear Polarizer
- Active Range: 450nm – 1,065nm
- Unique low cost Visible / NIR hybrid linear polarizer
- Polarize 740nm, 780nm, 850nm, 870nm, and 940nm LED’s
- Polarize 785nm, 808nm, 830nm, 905nm, and 980nm laser diodes
- NIR polarizer for solid state applications
- Low cost polarization solution for transmitters, receivers and detectors
- Polarize machine vision light source
- Economical large surface LED light arrays
- Not meant for imaging applications due to internal scatter
- Can be converted with PSA
