The Titanium coating consistently reflects less than 1% of the imaging light hitting the front surface of the filter while transmitting nearly 99%.Digital Ultra Clear.

The Tiffen Circular Polasizer is a sophisticated accessory that selects which light rays enter your camera lens. Once reflected, light rays become polarised, often with undesirable effects. Polarisers remove unwanted reflections from non-metallic surfaces such as water or glass, and also saturate colors, improving contrast.
