REVARCINE 4X5/138MM CIRC POLA FILTER
The Revarcine ROTA-TRAY 4x5.65/138mm Filter Tray with Circular Polarizer is a geared filter tray designed and manufactured from aircraft grade aluminum and poly materials to interface with the latest 4x5.65 matte boxes on the market today. Commonly referred to as a RotaPola, RotoPola or Rota-Pola, this geared tray allows for a use of a common 138mmm unmounted circular Polarizer in a rectangular 4x5.65 tray. Simply insert it into a top loading 4x5.65 size 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. The ROTA-TRAY also allows for rotation of a filter in matte boxes that do not feature a rotating filter stage or if a secondary rotating filter is needed in a non-rotating stage.
The ROTA-TRAY also has 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 dumb 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 low weight and profile design for maximum convenience.The Revarcine Circular Polarizer is a mid-efficiency Circular Polarizer constructed of Schott B270 glass featuring 38% transmission (1.5 average stop loss) and a special military spec hard Broadband Anti-Reflective Coating that minimizes reflections and resists scratches from everyday use for optimal image quality. The ROTA-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"+/-0.010"diameter and 0.135"+/- 0.005"thickness.
