a new type of lens material allows 180 degrees tiny lens - toni-a - 11-23-2021
Still in experimental phase, but a tiny lightweight 180 degree one element rectilinear lens that is sharp even at the borders, should revolutionise lens industry with the implications of the technique

Ok, so they have it working in the lab now, for monochromatic images, and with infrared light.
I reckon there are major hurdles to overcome to get it to work for images in colour, as the patterns need to be adjusted for each different wavelength. It is going to be interesting to see if they can actually overcome this, and how.

!80 degrees.... yet the video shows no such thing. Crisp imgaes... yet the video shows nothing even approaching "crisp". It is cool that they get any type of image at all, but this is very much still in its conception phase.
