FS ND Cinema FULL SPECTRUM NEUTRAL DENSITYnisi2024-01-30T10:19:32+08:00
The new NiSi Full-Spectrum Neutral Density Filter range (FS ND) transmits light evenly through the spectrum of ultraviolet, visible light and near-infrared wavelengths. It produces perfect neutral colors and retains fine granular detail without compromising other aspects of optical performance.

NiSi’s FS ND filter is made with environmentally sustainable optical H-K9L crown glass, which is equivalent to Germany’s SCHOTT N-BK7 and Japan’s HOYA BSC7 optical glass in terms of quality. The construction process involves precision annealing, carefully timed heating and cooling protocols, and prolonged holding times, which all work together to eliminate internal stress within the glass and prevent deformation. Compared to ordinary glass, H-K9L glass offers superior benefits such as high neutral light transmittance, excellent uniformity of physical and chemical properties, and precise optical constants.
The newly developed double-sided nano “Ti” (titanium) attenuation film and antireflection coating minimizes glare and reflection. It also greatly reduces or eliminates the reflection of light back and forth between the lens and adjacent filters.
NiSi FS ND
The filter edge is coated with a special matting imported from Japan.
This coating for optical lenses prevents ghosting and various forms of glare.

Captures true-to-life images.
Optical glass with precise flat and parallel surfaces that guarantee sharpness.
Exceptionally accurate and consistent exposure control.
Eliminates IR pollution on any camera.
Titanium Coating for long filter life.
Hydrophobic and oleophobic coating for easy and fast cleaning.
Cutting-edge anti-reflective coating minimizes flare and preserves overall contrast.
Optical properties are permanently stable and will not fade over time.
