BVO VIS DS Polarizer

Overcome the polarizer LED burn from intense modern light sources by using BVO VIS DS (formerly called BVO 125) robust dyestuff linear polarizer. Machine vision requires polarization to eliminate glare and new LED sources can burn traditional iodine based linear polarizer. Blue LEDs can bleach standard iodine polarizers while other environments such as automobiles require a higher temperature tolerance. Dyestuff polarizers are the best bet to ensure linear polarizer survival.
