The Heliopan 39mm 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. This results in a noticeable increase in the saturation of skies and foliage, as well as clearer imagery when photographing in hazy conditions. A linear polarizer differs from a circular polarizer in that it does not supports use of a camera's autofocus or auto exposure functions; it is best suited for use with manual cameras, such as view cameras, that are not dependent on internal mechanisms to determine focus or metering settings.
The front and rear surfaces of the filter both feature a single anti-reflection coating. Each coating helps to increase light transmission by reducing reflections, scattered light, and ghosting. Additionally, they offer protection to the filter substrate while helping to keep the glass clean for longer than uncoated glass.
This Heliopan filter is constructed from Schott glass for increased optical clarity and color fidelity. It features a brass filter ring for durability as well as jamming prevention.
- Reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface.
- Arrange and filter directionally polarized light perpendicularly to the reflected light allowing for the absorption of much of the light.
- Lessens haze in distant landscapes and provides more saturated, vivid colors.
- Strongest effect when used at a 90� from the sun.
- Single coatings on both the front and rear offer protection to the glass and help to improve light transmission and image quality.
- Constructed from Schott glass for optical clarity.
- Brass filter ring helps to prevent jamming and provides additional strength.
- Dual threading with 39mm front filter threads permits combining with other filters.
