NiSi HUC C-PL PRO Nano 82mm Circular Polarizer Filter

The NiSi 82mm Pro Circular Polarizer Filter is designed to minimize reflections and glare by eliminating light that has become polarized due to reflection from non-metallic surfaces. Sunlight naturally becomes partially polarized when it reflects off air molecules, leading to a scattering effect that manifests as haze. A polarizing filter effectively aligns and filters this directionally polarized light in a perpendicular manner to the reflected light, enabling the absorption of a significant portion of this light. Consequently, this results in a marked decrease in glare and reflections from non-metallic surfaces, while also enhancing the saturation of skies and foliage.

The primary distinction between a circular polarizer and a linear polarizer lies in the inclusion of a quarter wave plate alongside the linear polarizing filter. This quarter wave plate is essential for circularly polarizing the linearly polarized light, thereby facilitating the functionality of auto focus and exposure settings. When utilizing a linear polarizer, the breakdown and filtering of light can lead to inaccuracies in auto focus and exposure. However, with circularly polarized light, these functions can operate effectively.

Constructed from optical glass, the NiSi 82mm Pro Circular Polarizer Filter ensures clarity and color accuracy. It is equipped with a brass filter ring that allows for rotation to adjust the polarization intensity, enhancing both durability and resistance to jamming. Furthermore, each surface of the filter is treated with a layer of NiSi Optical Nano Coating, which improves the beading effect when exposed to water, thereby facilitating easier cleaning.

• Helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface.
• Polarizing filters arrange, and filter, directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of the light.
• Clears up haze in distant landscapes and provides more saturated, vivid colors.
• Strongest effect when used at a 90 angle from the sun.
• Circular polarizers are ideal for use with digital cameras and autofocus lenses where a linear polarizer will often disrupt auto exposure and focus features.
• NiSi Optical Nano Coating creates an improved beading effect when in contact with moisture for greater cleaning efficiency.
• 2 to 2.5x filter factor reduces exposure by 1 to 1.3 stops.
• Constructed from optical glass for clarity.
• Brass filter ring helps to prevent jamming, and provides additional strength.
• Filter ring can be rotated to adjust the intensity of the polarization effect.
• Side knurling to provide a more textured grip when mounting or removing filter from a lens.
• 82mm front filter threads allow for use with other filters.
• Plastic filter case for storage and transport.
