Active Range: 400 nm – 1,000 nm | High Durability Dyestuff | Doc: BVO.NIRHD.202501
BVO NIR HD is a high durability, dyestuff linear polarizer covering both the visible and NIR bandwidth from 400 nm to 1000 nm. The dyestuff architecture makes this polarizer inherently resistant to LED burn-in — the primary failure mode for standard NIR polarizers in high-intensity illumination applications. BVO NIR HD is ideal for machine vision illumination systems, automotive NIR cameras, semiconductor and PCB inspection, and any application where a polarizer is exposed to sustained high-intensity LED output. Available in a larger-than-A4 format for large panel laminations of NIR LED lighting banks.
