This 43mm MRC Basic Circular Polarizing Filter from B+W reduces reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. Light from the sun naturally becomes partially polarized due to reflecting off electrons in air molecules, causing it to scatter into what appears as haze. A polarizing filter arranges this directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of this light. This results in a noticeable reduction of glare and reflections from non-metallic surfaces and an increase in the saturation of skies and foliage. Objects and people behind surfaces such as shop windows and car windshields become visible again, a fascinating image enhancement without the need for image processing in post production.

B+W MRC Basic filters are equipped with the exclusive Multi-Resistant Coating (MRC) nano premium coating technology. This high-quality broadband coating is applied on both sides and enhances the optical imaging properties, allowing uniform and increased transmittance across the entire light spectrum to be achieved, with minimal physically induced remaining reflection. The nano all-round protection on the filter glass also ensures increased scratch resistance as well as extremely fast and easy cleaning for a long filter life.
