Variable Neutral Density Filter - Fits in most 4x5.65 matte boxes

The Brilliant² 4x5.65/138mm Variable Neutral Density Filter is 12mm thick and is designed to fit in 4x5.65" matte boxes that have at least two undivided slots (stages). 

It provides ND values between ND 0.6 (2 Stops) and ND 2.4 (8 Stops).

No Accidental Polarization in the Scene or Cross Polarization in the Camera

Our VNDs are constructed using two 138mm circular polarizers.  One of the polarizers rotates and the other is fixed.  The circular polarizers are oriented with their quarter wave retarders facing out, effectively de-polarizing on both sides which prevents accidental polarization effects in the scene and allows the Variable ND to be inserted in either orientation.

Water White Optical Glass with MC Coating

The Lindsey Optics Brilliant-Pol Polarizing Filters used in our Variable Neutral Density filters are constructed using Schott B270 "water white" optical glass and have a broadband multi-layer anti-reflection coating which dramatically reduces flare, stray light and ghost images caused by filter to filter reflection. Contrast and color saturation are increased. They are ground and polished to be very flat and will not cause distortions or focus shifts, even with long focal length lenses.   

Large Diameter Clear Aperture

The included large 138mm diameter polarizers give a large 5.1" clear aperture, useful even with wide angle lenses and large zoom lenses.

Quick and Sure No-Slip Rotation

Change of density can be done by spinning either of the two 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 the138mm Brilliant Pol Circular Polarizer filter is mounted. That main gear rests on internal Delrin™ rollers for smooth rotation no-slip rotation, The main gear is driven by aluminum thumb wheels that are geared with standard 0.8 pitch gear teeth for use with motorized wireless remote systems.

As with all circular polarizers, the Brilliant Pol Circular Polarizers are constructed with two internal components, a linear polarizer that will reduce reflections 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.

Works with our RotaPol Polarizer

When used behind our RotaPol, the Our Variable ND works beautifully and both polarization and neutral density can be controlled with motors and wireless FIZ system.  The Rotapola MUST be in front of the Variable Neutral Density filter (world side) for this to work.
