4"x5.65" Variable ND FilterSKU L-138-VARIABLEND
The Brilliant² 4x5.65/138mm Variable Neutral Density Filter is designed to fit in 4x5.65" matte boxes, occupying 2 slots in the matte box. It is constructed using two 138mm circular polarizers with MC Anti-Reflection Coating. One of the polarizers rotates and the other is fixed.
The Brilliant² Variable ND provides ND values between ND 0.6 (2 Stops) and ND 2.1 (8 Stops) with excellent neutral color. Visible light is attenuated as well as near infrared light from 700 nm to 850nm, giving good control of "IR Pollution" with camera sensors sensitive to infrared..
The unique tray mount design allows quick and easy insertion into the matte box. Because it's constructed with two circular polarizers, it functions perfectly when inserted in either orientation.
The handle has a standard 1/4 20 thread to allow mounting a motor for fade effects. If the motor is synchronized with the lens aperture a variable depth of field effect can be achieved.
The Brilliant² Variable ND works with Arri™, Bright Tangerine™, Chrosziel™ and Vocas™ and other professional cine matte boxes that have 2 or 3 filter stages.
