Less reflections, more intense colours Polarising filters give you some of the most interesting and important effects in photography. Therefore, they are part of the basic equipment of every photographer. With these filters you reduce reflections and ensure a clear, interference-free image, for example when photographing mirror-like non-metallic surfaces such as windows, glass display cases or water surfaces. In addition, polarising filters bring out colours better and achieve higher contrasts, for example between landscapes and blue skies. The result is vivid images with great radiance. High-end designs according to Kasemann. We offer high-quality polarising filters according to Kasemann, which are made from hand-selected pile films and carefully selected foil pieces. To ensure safe sharpness, the specifications of the optical components are tightly tolerated and the lenses are additionally ground and polished. These polarising filters are particularly suitable for high-speed, apochromatically corrected telephoto lenses and do not affect the recording quality.
