Behind the globally recognized B+W filter quality is a continuous process
of optimization and quality control which already begins with the raw glass
blocks. For the production of the high-precision B+W filters Schott colored
glass is used almost exclusively because Schott guarantees the very highest
glass quality.

In Bad Kreuznach, computer-controlled grinding and polishing machines
produce the highest filter quality from this raw material in an impressive
range of designs and diameters. Special production processes remain the
domain of the optimizing handcraft of experienced specialists. Strict quality
checks in all key production steps ensure seamless production standards.
B+W quality does not come about by coincidence, but is clearly defined: to
manufacture exactly plane-parallel filter discs without arching or wedge
errors (deviating thickness) which could lead to partial image blurring.
The filter glass must be completely smooth, because roughness results in
scattered light and an unwanted soft focus effect. B+W filter glass meets
the highest requirements of camera and lens manufacturers and guaran-
tees optimum imaging quality.

B+W is the first filter manufacturer in the world to offer MRC (Multi Resist-
ant Coating). This multi-layer coating is vapor-deposited in highly advanced
vacuum coating plants. It is extremely low-reflective and highly resistant to
scratching. But above all its unique dirt and water-repellent surface makes
cleaning the filters easier. In this way, filters can also perform a protective
function for the front lens.
The continuous new development and further development of the B+W filter
models and the final inspection of each individual filter mean that users can
achieve the best possible photographic results. It is therefore important to
give the same consideration to quality when buying a filter as when select-
ing your lenses. 60 years of know-how guarantee top filter quality to meet
global market standards. A brand promise we can be very proud of in Bad
Kreuznach.
