This 49mm High-Transmission MRC-Nano Master Circular Polarizer Filter from B+W helps reduce reflections and glare by filtering out light that has become polarized due to reflection from nonmetallic surfaces. Ambient light from the sun naturally becomes partially polarized due to reflecting off electrons in air molecules, causing the light to scatter into what appears as haze. A polarizing filter arranges this light perpendicularly to the reflected light, resulting in a noticeable reduction of glare and reflections from nonmetallic surfaces and an increase in the saturation of skies and foliage.
B+W's Master filter line products are equipped with the exclusive MRC nano premium coating technology. This high-quality broadband coating is applied on both sides and enhances the optical imaging properties to achieve a uniform and increased transmittance across the entire light spectrum, with minimal physically induced remaining reflection. The nano all-round protection on the filter glass ensures increased scratch resistance and extremely easy and fast cleaning.
