  • What's special about the Kasemann filter?
    The top quality polarising foils used in Kasemann type filters are neutral in colour and have a higher efficiency than conventional ones. They are cemented between high-grade optical glass. The resulting sandwich is then precision-polished again to achieve highly accurate plano-parallel surfaces. Subsequently they are edge-sealed to protect the foil against humidity.
  • MRC Multi Resistant Coating
    Each side of the filter has 7 anti-reflection coatings plus a protective layer which ensure maximum reflection and stray light reduction (residual reflection of just 0.5%). This ensures brilliant colours and high contrast, and the elimination of ghost images caused by back reflection from the camera sensor.
  • Precision engineered mount
    The 7mm deep brass mount is made on a CNC milling machine. The filter glass is held securely but without tension by a threaded retaining ring, and there is a front thread. Black hard-chrome plating with a matt black inside surface and engraved markings ensure long service.
