Schneider Optics 4x4 Circular True-Pol Polarizing Filter

Schneider's Circular True-Pol Polarizing filter for cameras which use polarizing elements in the beam-splitters of the viewing system, such as ARRI 435 and the Movie-Cam Compact.

Beam splitters send light in two directions: to an eye-piece and to a video tap. Light in a cameraメs viewing system can become polarized, and when a standard (linear) polarizing filter is attached to the lens, the light becomes cross polarized. This hinders visibility and may create total black-out of the viewing image and/or the video tap.

Schneider Circular Polarizers feature a two layer design to prevent this blackout. The first layer is made up of the same polarizing material used in all True-Pol filters; the second layer is a 1/4- wave retarder plate which effectively prevents cross-polarization.

To ensure correct placement on the lens barrel Schneider clearly marks the outer surface on all Schneider Circular True-Pol Polarizing filters.

Having an extinction ratio of ER 374, the Schneider Circular True-Pol is 12- times more effective than other polarizing filters, and is unmatched in its ability to:

  • Reduce glare and unwanted reflections
  • Saturate colors
  • Deepen blue skies
  • Improve contrast
  • Penetrate haze

The Circular True-Pol Polarizing filters enable you to achieve a level of optical performance previously unavailable to cinematographers.

The polarizing film in a Schneider Circular True-Pol filter is laminated between two pieces of Schneiderメs crystal-clear, water-white optical glass. The filter is protected against edge-chipping and delamination by Schneiderメs unique Edge Seal, which also effectively reduces edge-reflections and flare. The absolute clarity of the glass combined with advanced polarizing material make True-Pol filters particularly effective on demanding scenes, as when shooting through windshields in rigged-cars. On such shots, Directors of Photography have found that Schneider True-Pol filters capture more color saturation, wider tonal range and much more contrast inside the car. Like all filters in the Schneider line, Circular True-Pol filters are precision polished to the highest possible standards, meeting the most demanding specifications for optical flatness.
