A new type of flat, razor-thin telescope lens could transform deep-space stargazing by making it possible to mount lightweight but powerful telescopes onto aircraft and satellites, scientists say.

Tunability in lenses typically requires bulky components, but researchers have created a metasurface lens that uses a piezoelectric thin film to change focal length when a small voltage is applied.

Scientists have developed an impossibly thin telescope lens that addresses a key astronomical challenge in a new study funded by NASA and DARPA. When you purchase through links on our site, we may ...
