I really think they could have done better with `Visualization3.mp4`. The black and white ICCapture screen recording of an LED light (?) doesn't really do a whole lot to show off the achromatic capabilities of their lens.

How does it work?

seems to me it's a Fresnel Lens, unfortunately the article is behind a paywall to say more

I hope they point it at the night sky and see a green star. That would be a very exciting event, as naturally green stars are not possible. I know that if I was an advanced "angler fish" type of civilization, that's definitely the lure I would use in a dark forest universe. on that note i hope the scientists are not stupid enough to send a signal to that star.

Why would they detect a green star ?

If you look at the supplementary information document, there's more pictures.
There's definitely quite a haze around light sources. It seems they have tried applying some deconvolution to try to increase the sharpness, but the resulting images are still quite muddled.
Here's one of the libraries they used: https://github.com/apsk14/rdmpy
