B + W 82 mm F-Pro Kaesemann High Transmission Circular Polarizer MRC Filter F-Pro Kaesemann
B-W 82 mm high transmission circular polarizing filter helps reduce reflexes and reflections by filtering light that has been polarized due to the reflection of a non-metallic surface. Sunlight, of course, is partially polarized because of the electrons that are reflected in the air molecules, which causes the light to disperse in what appears as fog. A polarizing filter organizes, and filters, this light polarized directional perpendicularly to the reflected light, allowing the absorption of much of this light. This results in a notable reduction in glare and reflections of non-metallic surfaces and an increase in the saturation of the skies and foliage.
A circular polarizer only differs from a linear polarizer in that it contains a quarter-wave plane in addition to the linear polarizer filter. The addition of this room-wave plane is to circularly polarize the linearly polarized light for the use of auto-focus and exposure functions. Due to the way the light decomposes and filters with a linear polarizer, the auto focus and exposure accuracy deviate during use. When the light is polarized circularly, it allows the use of these functions. Kaesemann High Transmission (HTC) polarizing filters are equipped with polarized foils that provide a 99.5% light transmission that is cemented between flat and parallel optical glass. The resulting sandwich is precisely polished to achieve precise flat and parallel surfaces. Finally, they are sealed at the edges to protect the foil against moisture. To Avoid internal reflections and reflections, each glass surface includes several layers of reflective coating. This multidrug-resistant coating (MRC) also offers greater protection to the filter substrate and helps keep it clean for longer than with uncoated filters.
The B + W filters are made of Schott glass for greater optical clarity and color fidelity. This Filter features an F-Pro brass filter ring for durability and jam prevention. It Helps to reduce reflections and reflections by filtering the light that has been polarized due to the reflection of a non-metallic surface. The polarizing filters have and filter the polarized light perpendicularly to the reflected light, allowing the absorption of much of the light. It Clears the mist in distant landscapes and provides more saturated and vivid colors. The strongest effect when used at an angle of 90 ° of the sun. Circular polarizers are useful in combination with digital cameras and auto-focus lenses where a linear polarizer often interrupts automatic exposure and focus functions.
Multiple coating to avoid internal reflections and reflections while providing a light transmission greater than 99.5%. The filter factor from 2 to 2.8 x reduces exposure by 1 to 1.5 stops. Built in Schott glass for greater optical clarity. The F-Pro bronze filter ring helps prevent jamming and provides additional resistance. Plastic Box for storage and transport.
