SCHNEIDER 138MM Circular True-Pol Filter Unmounted 3.5mm – MPTV1084761 (68-019904)

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.
