Wine Country Circular Polariser (100mm system)

The Wine Country Circular Polariser (100mm system) helps to reduce reflections and glare by filtering out light that has become polarised due to reflection from a non-metallic surface. Mounted within a geared aluminium-alloy filter ring, it is made specifically to fit between a separately-available Wine Country Camera 10.0 cm Filter Holder and Wine Country Camera filter holder adapter ring. The filter holder's external knob integrates with the geared filter ring, allowing for the independent rotation of the circular polariser.

The light from the sun naturally becomes partially polarised due to reflecting off electrons in air molecules, causing the light to scatter into what appears as haze. A polariser 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 polariser 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.

For increased optical clarity and colour fidelity, the Wine Country Camera Drop-in Circular Polariser Filter is constructed from Schott glass. To prevent internal ghosting and reflections, each glass surface includes 16 layers of anti-reflection coating. These coatings offer further protection to the filter substrate and help it to stay clean for longer than with uncoated filters.
