Formatt Hitech 165 x 165mm Firecrest Circular Polarizer Filter
The 165 x 165mm Firecrest Circular Polarizer Filter from Formatt Hitech is compatible with a Lucroit 165 Pro-series filter holder. It 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.
To eliminate internal ghosting and reflections, each glass surface of the Formatt Hitech 165 x 165mm Firecrest Circular Polarizer Filter features 7 layers of anti-reflection coating. These coatings also offer greater protection to the filter and help it to stay clean for longer than with uncoated filters, resulting in an improved beading effect when in contact with water for greater cleaning efficiency.

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.
2x filter factor reduces exposure by 1 stop.
7-layer multi-coating prevents internal ghosting and reflections while providing an improved beading effect with water for more efficient cleaning.
Constructed from Schott glass for optical clarity.
Padded case included for storage and transport.
