Description
The Lindsey Optics Brilliant² RotaPol fits in 4” x 5.65” cine matte boxes and allows simple and effective rotation of the included 138mm Round Brilliant-Pol Circular Polarizer.
Large Diameter Clear Aperture
The included 138mm diameter Brilliant-Pol circular polarizer gives a large 5.1″ clear aperture. The filter is masked top and bottom, preventing stray light entering the 4×5.65 matte box. The large size of this rotating polarizer is useful even with wide angle lenses and large zoom lenses. It is dramatically more useful than other rotapola filters that use 4.5″ polarizers.
Geared Rotating Tray for Quick and Sure No-Slip Rotation
The 138mm Circular Polarizer is mounted in a 4×5.65 geared rotating filter tray using one stage in 4×5.65″ 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 1/4–20 thread in the handle.
Our superior mechanical design includes an all-aluminum main gear in which the 138mm 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 Rotapola you can have a rotating polarizer in your matte box, even if your matte box does not have a rotating filter stage. In matte boxes with a rotating stage, our Rotapola is quick to insert and once installed, it’s fast and easy to adjust, by hand or with a motor on the geared wheels. It does not cause any interference with rods in a rod mounted matte box.
Circular Polarization – Prevents Accidental Cross Polarization
The Brilliant² RotaPol is delivered with a mounted Brilliant Pol 138mm Circular Polarizer, a glass filter that has 38% transmission, resulting in a 1.5 stop light reduction. So it has a neutral density value of ND 0.45.
As with all circular polarizers, the Brilliant Pol Circular Polarizers are constructed with two internal components, a linear polarizer that will reduce reflections and increase color saturation when rotated and a “quarter wave plate” that spins the light entering the camera lens, preventing any cross polarization inside the camera and lens system.
Optional Motorized Control
With a Brilliant² RotaPola – easily pull polarization from a reflected image on a window to the drama behind the window. Wireless remote with a motor lets you do this smoothly and repeatedly.
The handle on our Brilliant² RotaPola has a standard 1/4 20 thread to allow mounting a motor. The motor can be connected to either of the two thumb wheel gears, which have standard 0.8 pitch gear teeth.
An Essential Filter for Enhancing Every Scene
Brilliant-Pol Polarizers are extremely efficient at reducing reflections on glass, water and other reflective objects. Choose to eliminate reflections or just tone them down to balance light levels in a scene.
Brilliant-Pols saturate blue skies and increase color saturation in landscapes by reducing micro-reflections in the scene. Multi-Layer Anti-Reflection Coating ensures brilliant contrast and freedom from filter to filter reflections.
Use it as a Variable Neutral Density Filter
You can also use our Brilliant² Rotapola as a variable ND filter by using it in combination with another polarizer in the matte box. When you do this, the Rotapol must be reversed so that “This Side Out” points toward the camera lens. This puts the Quarter Wave Plate in the Circular Polarizer on the front side of the filter, which prevents accidental polarization effects.
Anti-Reflection Coating – Easy-Clean, Water Resistant, Oil Resistant
Our broadband multi-layer anti-reflection coating (MC Coating) dramatically reduces flare, stray light and ghost images caused by filter to filter reflection. Contrast and color saturation are increased. Our coating is water resistant and oil resistant and is remarkably easy to clean. While we don’t recommend getting finger prints on your filter, with our coating they clean off quickly and easily.
Fits in Most Professional 4×565 Cine Matte Boxes. The Brilliant² RotaPol rotating polarizer works with Arri™, Bright Tangerine™, Chrosziel™ and Vocas™ TILTA MB-T12, Wooden Camera UMB-1 and other 4×5.65 professional matte boxes. It does not work with RedRock Micro™ matte boxes or with the Tilta Studio matte box.
