NiSi NIR-TICPL-77 Overview

Why and How to Use a Circular Polarizer Filter

The 77mm Ti Enhanced Circular Polarizer Filter from NiSi 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 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.

A circular polarizer only 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 is to circularly polarize the linearly polarized light for the use of auto focus and exposure functions. Due to how the light is broken down and filtered with a linear polarizer, auto focus and exposure accuracy become skewed during use. When the light becomes circularly polarized, it permits the use of these functions.

Ti Enhanced Circular Polarizer filters are constructed from optical glass for clarity as well as color fidelity. This 77mm Ti Enhanced Circular Polarizer filter features a titanium filter ring for enhanced durability while remaining lightweight. It includes corresponding 77mm front filter threads for use with other screw-on filters as well as a matte black inner rim to help ensure that reflections do not occur along the filter’s edge. To further prevent internal ghosting and reflections, each glass surface also includes an anti-reflective, hydrophobic Nano coating that results in an improved beading effect when in contact with water or oil for greater cleaning efficiency.
