The Circular Polariser HD MC Filter from H&Y Filters helps to reduce reflections and glare by filtering out light that has become polarised 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 polarising filter arranges and filters this directionally polarised 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 polariser only differs from a linear polariser in that it contains a quarter wave plane in addition to the linear polarising filter. The addition of this quarter wave plane is to circularly polarise the linearly polarised light for the use of auto focus and exposure functions. Due to how the light is broken down and filtered with a linear polariser, auto focus and exposure accuracy become skewed during use. When the light becomes circularly polarised, it permits the use of these functions.
The Circular Polariser HD MC Filter is constructed from Schott B270 glass for increased optical clarity and color fidelity. Each side of this filter includes 16 layers of coatings to prevent internal ghosting and reflections as well as to provide an improved beading effect when in contact with water or oil for greater cleaning efficiency. It also features an aluminum-alloy filter ring that can be rotated in order to adjust the intensity of the polarisation effect.

- Clears up haze in distant landscapes and provides more saturated, vivid colors
- Strongest effect when used at a 90° angle from the sun
- Circular polarisers are ideal for use with digital cameras and autofocus lenses where a linear polariser will often disrupt auto exposure and focus features
