True Pol Circular 4x4

The Tiffen 4x4" Circular Polarizer Filter 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.

This filter is non-coated, has approximately 40% average light transmission, and is designed to provide a polarization effect that is 15 to 20% greater than other Tiffen filters which only provide a linear or circular polarization effect and are not UltraPol filters.

The Tiffen 4 x 4" UltraPol Circular Polarizer Filter is constructed from Water White glass for increased clarity as well as color fidelity.
