This filter is used to reduce reflections of light from water and glass surfaces, while simultaneously enhancing color saturation.

The Irix Edge Circular Polarizer (CPL) filter is extremely useful for landscape and architectural photography, reducing reflections from non-metallic surfaces, emphasizing detail, and increasing the color density of images.

The glass surfaces of the Irix filter are covered with a multi-coated anti-reflective layer that keeps the image clear and full of natural colors.

The additional waterproof and oil-repellent coating protects them from stains and fingerprints.
