Nisi 4x5.65" True Color Linear Polarizing Filter NIC-4565-TCPL

Cinema True Color Linear Polarizing Filter

The NiSi 4x5.65" True Color Linear Polarizing Filter is a cinema-grade glass filter designed for matte boxes accepting 4x5.65 inch panels. It targets cinematographers and photographers who need to suppress glare from non-metallic surfaces while preserving the scene's native colour balance.

Linear polarisation limits

Linear polarising filters work by blocking directionally polarised light reflected from surfaces such as water, glass or foliage. They are incompatible with through-the-lens metering and autofocus systems that rely on beam-splitters, so they suit cinema cameras or manual-exposure workflows rather than typical SLR or mirrorless stills bodies.

Cine sealed edge and coatings

Cine sealed technology blackens the glass edge to seal the polarising film against moisture ingress and temperature-induced delamination. A waterproof coating on both faces repels water and oil, easing field cleaning. The 4 mm substrate thickness provides rigidity for repeated insertion in standard 4x5.65" filter trays without flexing.
