Cokin Evo circular polarizer filters are constructed from Schott glass for increased optical clarity as well as color fidelity, and promote nearly flat attenuation of visible and UV light. This 95mm Evo circular polarizer filter features a durable, lightweight, 7.50mm-thick aluminium-alloy filter ring assembly with a front ring that can be rotated to adjust the intensity of the polarization effect. These rings minimize the potential for vignetting, and the front ring also includes corresponding 95mm front filter threads for use with other screw-on filters.

To help eliminate internal ghosting and reflections, each glass surface of the 95mm Evo Circular Polarizer Filter features 16 layers of Cokin's EVERCLEAR 5 anti-reflection coating. These coatings are resistant to oil, dust, dirt, and scratches, offering greater protection to the filter and helping it to stay clean for longer than with uncoated filters. The coatings are also hydrophobic, resulting in an improved beading effect when in contact with water for greater cleaning efficiency.
