Flat, razor-thin telescope lens could change the game in deep space imaging — and production could start soon
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.
