black is the new black

I'm not an expert on applications of black stuff, but having ultra black coatings can help get away with complex optical designs where you would have flares or loose resolution to scattered light inside your tube assembly. Also an optical design that's difficult to pull off mechanically may be easier to manufacture if you just use this coatings inside the tube and on the baffling.

Follow-up serious question: if I paint my car with this stuff, can a policeman tag me with his radar gun? If I wear clothes impregnated with it, would it confuse a "smart" surveillance camera? I'm also thinking if I used it as war paint, a facial recognition cam would probably be awfully confused by what appears to be a hole in my face.
I love this line of thinking!! Also, if i were to dimple an an entire plane’s body like a golf ball, and paint it with this... how stealthy would that be?
Oh, about as stealthy as a metal golf ball, painted black?
Put it this way: If you shine a flashlight at a cosmetic hand mirror, does the flashlight shine back and hit you in the eyes? Now tilt the mirror so that the flashlight doesn't blind you.
Stealth surfaces are supposed to work like a tilted mirror.
Now imagine a polished chrome golf ball. If you shine a flashlight at it, you'll still catch a bounce from the flashlight reflection, even if the surface is dimpled.
Compare the chrome golf ball's performance to an icosahedron faceted with mirrors. The faceted platonic solid is less likely to shine the flashlight back at your eyes, depending on it's angle of rotation. And a dodecahedron would perform even better.

#36Well this is certainly bad news for anyone who invested $35k in a vantablack wristwatch: https://www.h-moser.com/en/collection/1801-1200-endeavour-pe...
In my opinion, if you could afford $35,000 for a Vantablack wrist watch, you can afford another $35,000 for this one too haha. I doubt many of those purchasers were on the bubble.
High end watches aren't priced like regular consumer goods; you can resell them for close to (and sometimes more) than you paid for them, so the "cost" is much much less than the price.
What's most interesting about this watch is the steel/vanta combo costs the same as the solid gold version without vanta. Apparently just that small bit of vanta costs more than a large chunk of gold right now.

Haha would this even be legal?
Nevermind - it’s not even feasible

While it may or may not be the primary motivation for research, I'd speculate that it's great for making stealth satellites.

It can be done for limited production, but it doesn't fully hide from LIDAR
