Single-element len's tech claims chromatic correction
But nothing said about other aberrations. Also, the structures on the surface, would it interfere with keeping it clean, or are they so small they wouldn't matter.

I can't think of one, but _that_ would be an application justifying a great expense for a special type of lens. John Savard |

Commercial exploitation is a strong driver with many potential, global applications. Organic meta-materials are also waiting in the wings. |

The market here isn't things like microscope objectives. The market is camera lenses in phones. I wouldn't be surprised at all to see metamaterial lenses like the one described here show up in that application within just a few years. |

The CPU in the iPhone X (64 bit 6 core) reportedly costs 2,750 pennies. And that’s Apple buying from Apple.

But when considering something like a nanostructure, a camera chip is probably a better example. The sort that is found in many consumer devices, and has a similar complexity to the metamaterial lenses, go for a couple of dollars. |
