To take high-quality pictures of the celebrities, astronomers normally want thick, curved lenses to bend the sunshine exactly. But researchers have designed a flat lens that may take sharp pictures of the evening sky due to billions of nanostructures within the materials. It is light-weight and resilient to wreck, so it might ultimately be included into satellites.
These so-called “metalenses” use metamaterials and are usually tons of of occasions thinner than standard lenses. One metalens can typically exchange a number of …
