B+W 77mm XS-Pro Kaesemann HTC Circular Polarizer MRC-Nano Filter:
B+W 77mm XS-Pro Kaesemann High Transmission Circular Polarizer MRC-Nano Filter helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. The light from the sun naturally becomes partially polarized due to reflecting off electrons in air molecules, causing the light to scatter into what appears as haze.

A circular polarizer only differs from a linear polarizer in that it contains a quarter wave plane in addition to the linear polarizing filter. A polarizing filter arranges, and filters, this directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of this light. This results in a noticeable reduction of glare and reflections from non-metallic surfaces and an increase in the saturation of skies and foliage.

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.

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.

It is constructed from Schott glass for increased optical clarity and color fidelity. Features a thin brass filter ring to minimize the potential for vignetting while enhancing durability and jamming prevention. To further reduce the possibility of vignetting when this filter is in use, the filter ring's outside diameter is slightly larger than the actual thread size. This may prevent the use of some lens manufacturer bayonet hoods.

Features: B+W 77mm XS-Pro Kaesemann HTC Circular Polarizer MRC-Nano Filter

  • Constructed from Schott glass for optical clarity
  • Strongest effect when used at a 90° angle from the sun
  • Feature 2 to 2.8x filter factor reduces exposure by 1 to 1.5 stops
  • Clears up haze in distant landscapes and provides more saturated, vivid colors
  • Nano coating provides an improved beading effect with water for more efficient cleaning
  • Multi-coated to prevent internal ghosting and reflections while providing over 99.5% light transmission
  • Reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface
  • Polarizing filters polarized light perpendicularly to the reflected light, allowing for the absorption of much of the light
  • Ideal for use with digital cameras and autofocus lenses where a linear polarizer will often disrupt auto exposure and focus features
