Haida 150x150mm Circular Polarizer Filter
Constructed from high quality Schott glass for increased optical clarity and color fidelity, the Haida Circular Polarizing 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 filters 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 form 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 us. When the light becomes circularly polarized, it permits the use of these functions.
This Haida 150x150mm Circular Polarizer Filter is compatible with Haida 150mm Filter Holder, Lee SW150 Mark I and II Holders, NiSi 150mm Filter Holders and many more!
