B + W POLARIZER FILTER 55MM F-PRO HTC KASEMAN MRC

B + W 55mm F-Pro Kaesemann High Transmission Circular Polarizer MRC Filter

The high-transmission B + W 55mm F-Pro Kaesemann circular polarization MRC filter helps reduce glare and glare by filtering light that has become polarized due to reflection from a non-metallic surface. Sunlight naturally becomes partially polarized due to the reflection of the electrons in the air molecules, causing the light to disperse in what appears as mist. A polarizing filter fixes, and filters, this directionally polarized light perpendicular to the reflected light, allowing the absorption of much of this light. This translates into a remarkable reduction in glare and reflections from non-metallic surfaces and an increase in saturation of the skies and foliage. A circular polarizer differs only from a linear polarizer, since it contains a fourth wave plane, in addition to the linear polarizing filter.

The addition of this quarter wave plane is to circularly polarize linearly polarized light for the use of auto focus and exposure functions. Due to how light is broken down and filtered with a linear polarizer, auto focus and exposure accuracy are skewed during use. When the light is circularly polarized, it allows the use of these functions. The high-transmission circular polarizing filters (HTC) from Kaesemann are equipped with polarizing sheets that provide a 99.5% light transmission that is cemented between flat parallel optical glass. The resulting sandwich is precision polished to achieve precise plane-parallel surfaces. Finally, they are sealed with edges to protect the sheet against moisture. To avoid ghosting and internal reflections, each glass surface includes multiple layers of antireflective coating.

This multi-resistant coating (MRC) also offers greater protection to the filter substrate and helps it stay clean longer than uncoated filters. B + W filters are manufactured with SCHOTT glass for greater optical clarity and color fidelity. This filter features an F-Pro brass filter ring for durability, as well as interference prevention. It helps reduce reflections and glare by filtering light that has become polarized due to the reflection of a non-metallic surface. The polarizing filters organize and filter directionally polarized light perpendicular to the reflected light, which allows the absorption of a large part of the light. Clears the haze in distant landscapes and provides more saturated and vivid colors. Stronger effect when used at a 90 ° angle from the sun.
Circular polarizers are useful in combination with digital cameras and autofocus lenses, where a linear polarizer often interrupts automatic exposure and focusing characteristics. Multi-coated to avoid internal ghosting and reflections while providing more than 99.5% light transmission. The filter factor of 2 to 2.8 x reduces the exposure by 1 to 1.5 stops. Constructed from SCHOTT glass for optical clarity. The F-Pro brass filter ring helps prevent clogging and provides additional strength. Plastic case for storage and transport.
