NiSi 138mm Mounted Polarizing Filter

The NiSi 138mm Mounted Linear Polarizer Filter is a linear polarizer made to fit directly into the 138mm donut of a matte box. It can be rotated before being locked down to offer variable amounts or polarization and works to increase colour saturation while reducing reflections off of non-metallic surfaces like water and glass. Polarizers also reduce distortion and control the transmission of light from computer screens.

The NiSi 138mm Mounted Linear Polarizer Filter has an aluminum frame that surrounds a piece of NiSi Water White glass with a polarization coating.
