The Hoya 37mm HD 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.

To prevent internal ghosting and reflections, the glass surface includes an 8-layer anti-reflective HD Multi-Coating. This offers further protection to the filter substrate and makes it water and oil repellent as well as scratch and stain resistant. This filter features a thin filter ring to minimize the potential for vignetting while enhancing durability and jamming prevention and has 37mm front filter threads. Additionally, it comes with a protective case.

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.
Eight-layer HD Multi-Coating to prevent internal ghosting and reflections. Also, it is water and oil repellent as well as scratch and stain resistant.
Glass is mounted with High Pressure Press Technology to ensure glass does not loosen up over time.
Plastic filter case for storage and transport.
