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.

To take high-quality images of the stars, astronomers usually need thick, curved lenses to bend the light precisely. But researchers have designed a flat lens that can take sharp images of the night ...

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.

Avantier’s Pancake lenses offer a cutting-edge optical solution tailored for next-generation Virtual Reality (VR) headsets.
