Description
This Rota-Pol Circular Polarizer is mounted in a geared rotating filter tray using one stage in 4 x 5.65" matte boxes. Rotation of the polarizer can be done by spinning either of the two geared thumb wheels by hand, or with a motor mounted on the 1/4"-20 thread in the handle. The mechanical design includes an all-aluminum main gear in which the filter is mounted. The main gear is supported by internal Delrin rollers for smooth, no-slip rotation. The main gear is driven by aluminum thumb wheels that have standard 0.8 pitch gear teeth for use with motorized wireless remote systems. In matte boxes with a rotating stage, the Rota-Pol is quick to insert and once installed, is fast and easy to adjust, by hand or by motor.
