POLARPRO QUARTZLINE – 82MM CIRCULAR POLARIZER

The 82mm QuartzLine Circular Polarizer Filter from PolarPro helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a nonmetallic 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 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 nonmetallic surfaces and an increase in the saturation of skies and foliage.

A circular polarizer differs from a linear polarizer in that it contains a quarter wave plane in addition to the linear polarizing filter. The addition of this quarter wave plane circularly polarizes the linearly polarized light for the use of autofocus and exposure functions. With circular polarization, autofocus and exposure accuracy are maintained.

This filter is constructed from quartz glass for enhanced durability. To prevent internal ghosting and reflections, 16 layers of anti-reflection coatings offer scratch protection to the filter substrate while promoting clarity and color fidelity. The coatings also improve beading when in contact with water or oil, allowing for more efficient cleaning.

The quartz glass is set within a brass filter ring with side knurlings that can be rotated to adjust the intensity of the polarization effect. Together, the brass material and knurlings prevent jamming and provide additional strength, as well as a textured grip when mounting or removing the filter from a lens.

Features:

• Helps reduce reflections and glare from non-metallic surfaces.

• Polarizing filters arrange and filter directionally polarized light perpendicularly to reflected light, absorbing much of it.

• Clears haze in distant landscapes and provides more saturated, vivid colors.
