RENT Lindsey Optics 4x5.65/138mm Brilliant2 Variable Neutral Density Filter

Brilliant 4x565 Variable Neutral Density

Fast and Flexible Variable ND
• Change the ND value fast as the light changes or quickly find just the right ND value to get the desired lens aperture and depth of field.
• Unlike other Variable NDs, it works when inserted in either orientation. So insertion is fumble free.
• Optional motor mounting allows smooth and repeatable fade effects.
• 2 to 8 stops of light control.
• Cuts Both Visible and Near Infrared Light.
• Broadband Multi-Layer Anti-Reflection water resistant and oil resistant coating.

2 - 8 Stops of Light Control - Including Near Infrared
The Brilliant2 Variable ND provides between 2 stops and 8 stops of Variable Neutral Density light control, with ND values between ND 0.6 (2 Stops) and ND 2.4 (8 Stops) with excellent neutral color. The desired ND value is obtained by rotating either of the geared thumb wheels by hand or with a motor.

Cuts Near Infrared Light
Visible light is attenuated and near infrared light from 700nm to 850nm is also reduced, giving good control of "IR Pollution" with camera sensors sensitive to infrared.

Broadband Multi-Layer Anti-Reflection Coating
Our Broadband Multi-Layer Anti-Reflection coating prevents internal filter-to-filter reflections within the Variable Neutral Density Filter and with any other filter in the matte box. Contrast is maintained and ghost images are prevented. Our coating is water repellant and oil repellant which results in a filter that is easy to clean and easy to keep clean.

Large 5.1 Inch Clear Aperture
The two included Brilliant Pol Circular Polarizers have a large 5.1 inch clear aperture, perfect for use with wide angle lenses and large diameter zoom lenses. The vertical dimension is masked at the top and bottom to prevent stray light from entering the matte box.

Unique Construction
The Brilliant2 Variable Neutral Density Filter is constructed using all aluminum body and gears. A Brilliant-Pol Circular Polarizer is mounted in the large main gear, which runs on Delrin rollers for smooth no-slip rotation. A second Brilliant-Pol Circular Polarizer is mounted in a fixed position. The unique tray mount design allows quick and easy insertion into 4x565" matte boxes.

Insert in Either Orientation
Because it's constructed with two circular polarizers, it functions perfectly when inserted in either orientation. As with all circular polarizers, the Brilliant-Pol Circular Polarizers used in the Brilliant 2 Variable ND are made with 2 components laminated between sheets of glass. There's a linear polarization element that does the main work of polarization and a "quarter wave plate" that spins the light to avoid unwanted artifacts. The Brilliant 2 Variable ND is assembled with the quarter wave plate of each polarizer facing outward. The outward facing circular polarizer prevents any accidental polarization in the scene. The inward facing polarizer prevents any cross polarization in the camera.

Optional Motorized Control
The handle has a standard 1/4 20 thread to allow mounting a motor for wireless remote control for Jib and Crane operation, as well as smooth fade effects. By synchronizing motorized variable ND with the lens aperture a variable depth of field effect can be achieved.

Fits in 4x5.65" Matte Boxes - Uses 2 Slots
The Brilliant2 Variable ND is designed to fit in 4x5.65" matte boxes, occupying 2 slots in the matte box. The Brilliant2 Variable Neutral Density Filter works with Arri, Bright Tangerine, Chrosziel and Vocas and other professional 4x5.65 cine matte boxes that have at least 2 filter stages.
