• 100mm System Optical Glass Filter,Can be used for Canon 16-35,Canon 24-70,Nikon 24-70,NiKon 70-200 and other 52mm,55mm,58mm,62mm,67mm,72mm,77mm,82mm lenses,compatible with Lee Cokin Hitech Singh-Ray and other brand holder
• 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.
• 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.
• Nano attenuation coating,Water&oil repellent coating,Ultra low color shift,Ultra low reflection
• NiSi square IR ND filters are not only coated but we have also added a Japanese fire-proof foam gasket to ensure there is no light leakage.

NiSi 100X100mm (4x4) Square IR Neutral Density Filters. 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. 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. 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. NiSi square IR ND filters are not only coated but we have also added a Japanese fire-proof foam gasket to ensure there is no light leakage. These filters are fully compatible with Lee FK Holder, Cokin Z-Pro, Hitech 100mm, NiSi 100mm and other 100mm Holders!
