Product Description

The HOYA 37mm CIRC-POL HD 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.q

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 constructed from optical glass for clarity as well as color fidelity and features a thin, aluminum-alloy filter ring that can be rotated to adjust the intensity of the polarization effect. To prevent internal ghosting and reflections, eight layers of anti-reflection multi-coatings are applied to the filter's glass. These coatings also offer greater protection to the filter substrate and help it to stay clean for longer than with uncoated filters.
