Interesting "lens" - maybe more in common with a fresnel lens than a conventional one in as much as it's completely flat, but this one is a bunch of 0.001mm vertical cylinders growing out of flat base (see photo in article). I guess it works by witchcraft. > The manufacturing method of this metalens is also worth mentioning. Using next-generation nanoimprint semiconductor manufacturing equipment developed by Canon, it is possible to mold the material by pressing it against the material like a stamp. It can be produced much faster and at a much lower cost than regular lenses
