Schneider Optics Circular True-Pol - Filter - circular polarizer

Schneider offers a 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 eyepiece and to 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 blackout 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.
