The Lindsey Optics Brilliant² Rota Pol, sometimes called RotaPola is designed to fit 4” x 5.65” cine matte boxes and allow simple and effective rotation of the included 138mm Round Brilliant-Pol Circular Polarizer. Rotation of the polarizer can be done by spinning either of the two thumb wheels by hand or with a motor mounted on the 1/4–20 thread in the handle.
