Researchers have created a special flat lens that shapes light into an optical needle—a thin beam that stays tightly focused ...

Paper-thin optical lenses simple enough to mass produce like microchips could enable a new generation of compact optical devices. Researchers have fabricated and tested flat lenses called Fresnel zone ...

Researchers have shown that consumer-grade 3D printers and low-cost materials can be used to produce multi-element optical components that enable super-resolution imaging, with each lens costing less ...

(Nanowerk Spotlight) Optical lenses play a crucial role in a vast array of applications, from microscopy and astronomy to photography, medical devices, and machine vision systems. Traditionally, the ...
