Built into a single-stage, self-contained unit, the Revar Cine Rotating Polarizer, or Rota-Pola, is a compact, easily-rotatable polarizing solution for most matte boxes that accept 4×5.65″ filters. Rather than requiring a full 4×5.65″ glass filter, the Rota-Pola tray uses an included 138mm-diameter filter which sits inside the rotating tray. If the polarizer needs to be adjusted, simply rotate one of the geared wheels that extend from the top of the tray on either side.
The included filter is a 138mm mid-efficiency circular polarizer, manufactured from Schott B270 glass. It features 38% transmission (1.5 stops of light loss) and Broadband anti-reflective coating for reducing unwanted flares. The tray itself has a lightweight and rigid aluminum construction.
Simply insert it into a top-loading 4×5.65 matte box tray slot and spin the gear on either side of the filter tray to rotate the filter inside. This allows for easy rotation of the filter without the need for cumbersome locking and unlocking of a rotating filter stage. This also allows for rotation of a filter in matte boxes that do not contain a rotating filter stage, or if a secondary rotating filter is needed in a non-rotating stage.
The Rota-Pola Tray also boasts features missing from other competitive products, such as standard 0.8 pitch gears on both sides of the filter tray for use from either the operator or assistant side of the camera, a 1/4-20 female threaded hole for mounting of a wireless follow focus for remote crane or jib operation of the filter, and an overall lightweight, low-profile design.
The tray is also available with no glass so you may choose to purchase your own Polarizer or Special Effect filters from leading filter manufacturers. Simply order an unmounted 138mm filter and confirm that it has a dimension of 5.236″ diameter (+/-0.010″) and 0.135″ thickness (+/- 0.005″).
Perhaps the largest innovation with the Rota-Pola is the price. Compare at an average savings of 40%-70% to competitive products with more features and freshly updated design for today’s cameras and matte boxes.
Compatible with Bright Tangerine, Arri, Vocas, Chrosziel, O’Connor O-Box, and many other matte boxes on the market today. Not compatible with RedRock Micro matte boxes.
