BVO UHC Polarizer

BVO UHC is our flagship visible linear polarizer and offers very high transmission with ultra high contrast over the visible spectrum. This absorptive type linear polarizer is also available with or without pressure sensitive adhesive (PSA) and an anti-reflection coating option directly on the film. BVO UHC performance covers almost all modern day applications requiring polarization control.
