“Metalens” breakthrough could lead to flat, cheaper lenses
There has been a surge of interest in camera sensors and lenses of late, partly because of the equally growing interest in smartphone cameras. But while smartphones are indeed becoming more and more capable in that area, they are limited by the laws of physics and current manufacturing capabilities. One of the hardest to get right are the lenses but inventors, lead by r professor Federico Capasso, may have finally come upon an answer that will yield not not only flatter and cheaper lenses but also better ones that can outperform even those used in top of the line research microscopes.
