BVO UV DS Polarizer
BVO UV DS is a high durability dyestuff ultraviolet linear polarizer suitable in additive manufacturing specifically for liquid crystal panel 3D printing. Large format sheet polarizer size allows for 4K or 8K panel laminations with precision alignment of transmission axis. BVO vertical integration covers panel modifications, optical engineering and UV DS polarizer laminations.
