BVO 125 Polarizer

Overcome the polarizer LED burn encountered by new intense light sources by using BVO 125 robust dyestuff linear polarizer. Machine vision requires polarization to eliminate glare and new LED sources can burn traditional iodine based linear polarizer. Some caustic environments such as blue LEDs bleach standard iodine polarizers while other environments require a higher temperature tolerance. Dyestuff polarizers are the best bet to ensure linear polarizer survival.
