Nisi IR ND64 (1.8) 150*150mm Square Filter (6 Stop)
- Ultra Low Colour Cast, Ultra Low Reflection
- Provide 6-stop light reduction
- No Vignetting
- High Definition
- Nano Coating on Both Sides, Water & Oil Repellent
- Environmental Optical Lens glass (H-K9L
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.
