A nano coating suppresses stray light.

Similar technology could find its way into consumer optics, improving performance.
NASA engineers have produced a material that absorbs on average more than 99 percent of the ultraviolet, visible, infrared, and far-infrared light that hits it
Sounds like it would make one heck of a ND filter! ;)

I like the idea of back-utilization; using new technology in old/obsolete applications. I think it would be cool to build a box camera with a nanoblack coating inside.

Perhaps a cure for Schneideritis?

It has. Our heliopan SH-PMC filters and our Rodenstock HR Digital super MC filters both have a nano coating on the top layer on both the top and bottom of the filter. This coating is hydrophobic and oleophobic so ot repelas moisture, oils, dust, fingerprints and keeps the filters cleaner and makes them easier to clean. The nano layer is totally optically neutral in color.

Thanks, Bob! That's very interesting.
