A new metalens design developed by researchers at MIT, which is able to change its focus without tilting or moving forward or backward, may find use in miniature heat scopes for drones, ultracompact thermal cameras for cellphones, and low-profile night-vision goggles, its developers said. The lens technology uses heat to focus in on different objects, operating in the infrared band.
In current architectures, glass must move for a lens to be focused onto an object or at a point.
To create the lens, researchers looked to previous advances with GST (germanium-antimony-tellurium), a material commonly used in rewriteable CDs and DVDs and favored for its ability to shift between transparent and opaque states when heated by laser…READ MORE
