The B+W filter manufacturing company was founded in Berlin in 1947 by business partners Biermann and Weber. In 1985 the merger with the Jos. Schneider Optical Works in Bad Kreuznach expanded the B+W line of products with optical filters for science and technology. It also generated significant progress in multi-layer coating systems (MC). As a result, B+W became the first manufacturer of filters in the world to offer the innovative water- and dirt repelling MRC multi-layer coating process, which, in addition to its reflection-preventing qualities is also regarded as being especially scratch-resistant.
In Bad Kreuznach, the most modern fabrication machines produce highly precise filters in an impressive variety of types and diameters. Quality controls are integrated at all key stages of the production process, and a final inspection of every individual filter ensures the renowned high B+W quality standard. At B+W, our commitment to our guarantee and service are taken seriously. Continuous improvements and new developments enable users to achieve their best possible images. By comparison, a cheap filter can reduce the imaging performance of a high-quality lens quite dramatically! Therefore, consider the quality of a filter as seriously as you would consider the choice of your lenses – look for the B+W brand, because the quality of the image depends upon what is in front of the lens!
