Metasurfaces enable improved optical lens performance

Producing the perfect color images we need and love often requires multiple, heavy lenses so that each color focuses in exactly the same plane. Now engineers have developed a new theory that solves the problem using a single thin lens comprised of gradient index materials and metasurface layers to properly direct the light.

A super resolution view of chemical reactions

Researchers have demonstrated, using a super resolution microscopic technique, how to follow chemical reactions taking place in very small volumes. The method of analysis is the first to make it potentially possible to observe reactions not only inside living cells, but even within individual organelles, such as cell nuclei.
