Pol Filters

Why use polarizing filters?

Polarizing filters like our Linear and Circular True-Pol® are multi-talents that reduce glares, haze as well as unwanted reflections. On top of this, they also improve contrast and provide saturated colors. 

And this is how polarizers work: Polarizing filters transmit certain planes of oscillation and absorb others. The strength of the effect can be adjusted by rotating the filter. Generally, only perpendicular waves pass the polarizer, which can lead to light loss depending on the filter's orientation. 

At Schneider-Kreuznach, we offer both linear and circular polarizers with high extinction ratios, called Linear True-Pol® and Circular True-Pol®. Due to the absolute clarity of the glass and the advanced polarizing material, both filter types are effective on demanding scenes like shooting through windshields or in big landscape environments. 

Autofocus-Systems and Beamsplitters
Please note that linear polarizers like our Linear True-Pol® are only suitable for Non-AF systems and must not be used with beamsplitters. However, due to an additional 1/4 wave retarder,  our Circular True-Pol® is also compatible with beamsplitting and autofocus systems. 

Circular True-Pol®

  • High extinction ratio
  • Reduces glares, haze and unwanted reflections.
  • Provides saturated colors and improves contrast
  • Works with beamsplitting and autofocus (AF) systems

Linear True-Pol®

  • High extinction ratio.
  • Reduces glares, haze and unwanted reflections
  • Provides saturated colors and improves contrast
  • Only for non AF systems! Do not use with AF Systems or beamsplitters. Choose Circular True-Pol® for those
