B+W 72mm XS-Pro Circular
Polarizer MRC-Nano Filter:
B+W 72mm XS-Pro Circular Polarizer MRC-Nano Filter is 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.
