High Transmission Circular (HTC) 

Kaesemann High Transmission Circular (HTC) polarizing filters are fitted with polarizing foils which provide 99.5% light transmission that are cemented between plano-parallel optical glass. The resulting sandwich is then precision-polished to achieve accurate plano-parallel surfaces. Finally, they are edge-sealed to protect the foil against humidity.

Multi-Resistant Coating (MRC)

To prevent internal ghosting and reflections, each glass surface includes multiple layers of anti-reflection coating. This Multi-Resistant Coating (MRC) also offers further protection to the filter substrate and helps it to stay clean for longer than with uncoated filters. The Nano coating associated with XS-Pro filters provides an additional eighth layer over the MRC, resulting in an improved beading effect when in contact with water for greater cleaning efficiency.
