Flat lens
« on: July 06, 2018, 04:16:00 AM »

Brought to my attention by http://image-sensors-world.blogspot.com/

"Harvard University Prof. Federico Capasso and his group present "a single flat lens that can focus the entire visible spectrum of light in the same spot and in high resolution.
Professor Federico Capasso and members of the Capasso Group explain why this breakthrough in metalenses could have major implications in the field of optics, and could replace bulky, curved lenses currently used in optical devices."

This is nowhere near the first paper on this technology.  I read papers on it all the way back in 2014 and there was excitement on some photo forums.  This article basically regurgitates the same stuff in 2018 that was written back then and from reading this, it doesn't feel like we are any closer to a commercialization of this technology.  Hope I'm wrong, it would be awesome to have a lightweight 800mm large effective aperture lens :)

I would assume that if one can do a flat lens one can do it for any size sensor ...
