HD nano CIR-PL coating has the advantage of being one of the hardest, scratch and stain resistant coating in the world. The HD nano coating is 200% harder, resulting in increased durability and protection. The highly transparent HD nano CIR-PL polarizing film has 25% better light transmission than the standard polarizing film used in current photographic filters. This means that nearly 1/2 stop more light enters the lens with the same polarizing effect, maintaining the color balance of a standard circular polarizer while improving contrast and clarity.
