Successfully funded in kickstarter.Com in 2016, the aurora Powerxnd 2000 filters are now available in eBay. With the best light reduction and resolution capabilities, Powerxnd 2000 filters can be used in a wide variety photography as well as video applications. The Powerxnd 2000 has up to 11 stops (nd 2000) of light reduction capability which has been only available with fixed neutral density (nd) filters until now whereas commercially available variable nd filters only have up to 6 stops (nd 400) capability. Designed in California, Powerxnd 2000 has an innovative filter frame design which reduces the overall profile of the filter. This reduced profile is important for keeping igniting on wide angle lenses to minimum. The filter frame of the Powerxnd 2000 is optimized to reduce height and volume. With a filter height of 5.5Mm when mounted on a lens, the Powerxnd 2000 is about half the height of other commercially available variable nd filters and smaller overall. Multiple layers of Nano coating technology are applied to glass surfaces for anti-reflection purposes, thus provides protection to filter surfaces. The aurora Powerxnd filters are built from aerospace grade aluminum frames with computer numerical control lathes (cnc) for mechanical precisions and treated with anode oxidation process for corrosion protection. Extended temperature range lubricant is applied in the assembly process so the final products have smooth and yet dampen rotation handling for all weather applications.
