B+W, the leading filter manufacturer produces high-precision filters in a wide range of types and diameters using the latest production equipment. Made almost exclusively from perfectly homogenised Schott glass, B+W filters are available with single layer multi-coating (MC) or water-resistant and dirt-repelling multi-resistance coatings (MRC). The MRC multi-layer coating virtually eliminates all surface reflections on both sides of the filter, allowing maximum light transmission whilst providing very high scratch resistance.
Eliminates reflections from non-metallic surfaces such as water, glass etc...
Light moves through space in straight lines, vibrating as waves in many different directions. Light which is polarized, however, only vibrates in one plane. A polarizing filter or “polarizer” is a lens filter which polarizes light along one plane. This can cut non-metallic reflections and enhance contrast under certain conditions.
Polarizing filters contain a layer of polarizing material which is laminated between two glass circles and mounted in a frame. You can then rotate this filter, which affects the amount of light passing through. Even at their “brightest” setting, however, polarizing filters reduce the amount of light entering the lens - they always cost a a stop or so of light.
