NiSi 4×5.65" Full Spectrum ND 0.3

Advanced Full-Spectrum Light Control

The NiSi 4x5.65" Full Spectrum ND 0.3 is engineered for cinema professionals who demand absolute color fidelity. Unlike standard filters, the FS ND range transmits light evenly across the ultraviolet, visible, and near-infrared spectrums. This ensures perfect neutral colors and retains fine granular detail without compromising optical performance.

Premium H-K9L Optical Glass

Constructed from environmentally sustainable H-K9L crown glass, this filter matches the quality of industry-standard SCHOTT N-BK7. Each filter undergoes precision annealing and carefully timed heating protocols to eliminate internal stress. This meticulous process prevents glass deformation and ensures high neutral light transmittance with excellent physical uniformity.

Innovative Titanium Nano-Coating

The newly developed double-sided Ti (Titanium) attenuation film and anti-reflection coating minimize glare and ghosting. This technology effectively eliminates light reflection between the lens and adjacent filters, preserving contrast in challenging lighting conditions. Additionally, the hydrophobic and oleophobic layers make the surface easy to clean and resistant to the elements.

Professional Finishing

To further enhance image quality, the filter edges are treated with a specialized matting imported from Japan. This coating prevents internal reflections and ghosting, ensuring your footage remains crisp and clear.
