Lindsey Optics Brilliant2 Rota-Pol Circular Polarizer - 6.6 x 6.6

The Lindsey Optics Brilliant² Rota-Pol is a circular polarizer that fits in 6.6" x 6.6" cine matteboxes, allowing simple and effective rotation of the included 161mm Round Brilliant-Pol Circular Polarizer. The filter features a broadband, multi-layer, anti-reflection coating with 38% transmission for a 1.5 stop light loss. Its large, 6.25" clear aperture is compatible with wide angle lenses and large zooms, and is noticeably more versatile than other rotating polarizer filters with 6" diameter round filters (5.8" clear apertures).

The 161mm Circular Polarizer is mounted in a geared, rotating filter tray, occupying just one stage in 6x6 matteboxes (particularly useful when utilizing a clip-on mattebox). Rotation of the polarizer can be accomplished by spinning either of the two geared thumb wheels by hand, or with a motor mounted on either of the two 1/4"-20 threads in the handle. The thumb wheel gears are engraved with letters A through H and one rotation of the thumb wheel gear provides a 90° rotation of the polarizer.

Lindsey Optics' superior mechanical design includes an all-aluminum main gear, in which the 161mm Brilliant-Pol Circular Polarizer 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 with standard 0.8 pitch gear teeth for use with popular motorized wireless lens control systems.
