NiSi Filters Glass 150x170mm Nano Multicoated Reverse Graduated IR ND 0.9 (3-Stop) Filter GND8
World’s first Nano coated 150x170mm graduated ND filter, the NiSi IR ND for Digital imaging utilizes an exclusive Nano dual side coating technology, making for pristine image quality. The optical glass (H-K9L) is cured by a fine annealing process and a double sided optical grinding and polishing process help to ensure a quality high definition rating. Other filters are produced with lamination between two panes of glass, this causes color shift, higher reflection, and less image control, unlike the NiSi IR ND Filters.The NiSi Graduated Neutral Density filters adopt our exclusive Nano dual sided gradual coating, this means ultra violet to near-infrared light can pass through evenly, ensuring a perfectly neutral effect. NiSi filters are precision cut, polished and optically processed to allow for extreme flatness and high parallelism for the highest quality glass, image quality and image crispness. The Optical Nano Coating provides for a perfectly neutral filter that has no color shift or color cast. This optical Nano coating is also anti-glaring and anti-reflective, alleviating solar glare. This technology was developed for the NiSi IR ND exclusively by NiSi Filters. This is a breakthrough in the world of Digital Imaging.
These filters are fully compatible with Lee SW150 Mark I and Mark II Holders and Nisi 150mm Holders.
