The Lindsey Optics Brilliant2 1 Stop Rota-Pol is a circular polarizer that fits in 4x5.65” cine matte boxes and allows simple and effective rotation of the included 138mm Round 1 Stop Brilliant-Pol Circular Polarizer.

Our 1 Stop Pols absorb less light than our standard polarizers. When it's the end of the day and you're losing the light, the 1 stop loss allows control of reflections in difficult lighting conditions. 

Large Diameter Clear Aperture

The included 138mm diameter Brilliant-Pol circular polarizer gives a large 5.2" clear aperture. The large size of this rotating polarizer is useful even with wide angle lenses and large zoom lenses. It is noticeably more useful than other rotapola filters that use 4.5" diameter polarizers.

Geared Rotating Tray for Quick and Sure No-Slip Rotation

The 138mm Circular Polarizer is mounted in a geared rotating filter tray using one stage in 4x5.65" 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 ¼ 20 thread in the handle. 

Our superior mechanical design includes an all-aluminum main gear in which the 138mm 1-Stop 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 that have standard 0.8 pitch gear teeth for use with motorized wireless remote systems.

With our Brilliant2 Rota-Pols you can have a rotating polarizer in your mattebox, even if your Clip-On matte box does not have a rotating filter stage.

In matte boxes with a rotating stage, our Rota-Pols are quick to insert and once installed, they are fast and easy to adjust, by hand or with a motor.
