This Rota Tray with 138mm Circular Polarizer from Revar Cine fits in ARRI-standard-compatible 4 x 5.65" matte boxes. With an 0.8 MOD gear on each side of the filter tray, you can rotate the circular polarizer either by hand or by using optional motors. The circular polarizer helps prevent optical defects that can occur when using a linear polarizer with optical relay or electronic capture systems. The filter features anti-reflective coating for improved light transmission.
