Overview
The Schneider Circular True-Pol Polarizing Filter - 4X5.65 is designed for use with cameras that feature polarizing elements in the beam-splitters of the viewing system, such as ARRI 435 and the Movie-Cam Compact. This filter may also be required on certain digital cameras with complex optical blocks such as the Sony PMW-EX1, PMW-EX3, and PDW-700, which polarize the red and blue channels more than other cameras (and therefore require a circular polarizer to prevent cross-polarization and associated color shift in the image).
Beam splitters send light in two directions: an eye-piece and a video tap. Light in a camera’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 dual layer design to prevent this blackout. The first layer is made up of the same polarizing material used in all True-Pol filters, while the second layer is a 1/4-wave retarder plate which effectively prevents cross-polarization.
