The Tiffen 5 x 5" Linear 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 linear polarizer differs from a circular polarizer in that it does not contain an additional quarter wave plane. The addition of a quarter wave plane is to circularly polarize 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, in-camera 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 recommended when not using in-camera exposure metering or autofocus. It is non-coated and delivers approximately 40% average light transmission.

Tiffen filters are made using ColorCore technology; a process that involves laminating the filter substrate between 2 pieces of optical glass and grinding flat to a tolerance of 1/10,000th of an inch.

What is the difference between a Linear and a Circular Polarizer?

A Circular Polarizer is a Linear Polarizer with a 1/ 4 wave plate retarder added to the back of the polarizer foil. Circular Polarizers are necessary when using any camera that has a beam splitter which is used for internal light meter reading or a video tap. The beam splitter polarizes light and depending upon the position of the polarizer, you may cause double polarization and therefore result in inaccurate meter readings, in the case of a video tap a black out. Circular Polarizers are also necessary for auto focus cameras.

TIP: In any case in which linear polarizing filters suffice, circular polarizing filters can also be used, but not the other way around.
