SCHNEIDER 6.6X6.6 Circular True-Pol Filter - MPTV1082382 (68-013166)
Polarizer reduces glare and unwanted reflections, improves contrast, penetrates haze at long distances, deepens blue skies, and helps maintain colour saturation.
SCHNEIDER 6.6X6.6 Circular True-Pol Filter - MPTV1082382 (68-013166)
CIRCULAR TRUE-POL®
- High extinction ratio.
- Prevents cross-polarization.
- Reduce glare and unwanted reflections.
- Saturate colours and improve contrast.
- Penetrate haze.
- For use with AF Systems.
The filter is constructed by laminating the polarizing film and a 1/4-wave retarder plate between two sheets of clear water-white optical glass. An edge seal process is then used to guard against edge chipping and delamination, as well as contribute to reducing-edge reflections and flare. This filter suppresses reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface, which results in a noticeable increase in the saturation of skies and foliage, as well as clearer imagery when working in hazy conditions.
FEATURES
• Prevents cross-polarization
• Reduce glare and unwanted reflections • Saturate colours and improve contrast
• Penetrate haze
USP
High extinction ratio.
Application
Compared to the traditional Linear True-Pol®, this Circular True-Pol® is ideal for preventing viewfinder blackout when used with cameras featuring polarizing elements in the beam-splitter of their viewing system. Circular polarizers are ideal for use with digital cameras and autofocus lenses whereas a linear polarizer will often disrupt auto exposure and focus features.
The effect of a polarizer lies in the transmission of only certain planes of oscillation while absorbing others. By rotating the polarizer can be adjusted to the wanted effect strength. Polarizers allow only perpendicular waves to pass the filter so there is some light loss depending on the orientation of the filter.
Circular polarizers are ideal for use with digital cameras and autofocus lenses whereas a linear polarizer will often disrupt auto exposure and focus features. A circular polarizer darkens skies and provides colour and contrast enhancements. One-stop polarizers are ideal for shooting in low light situations such as indoors or at night, where polarization is still needed and no more than the one-stoplight loss is important
