World’s Tiniest Lens - 3D Printed & Twice The Width of A Human Hair

3D printing smallest lens

The world’s tiniest lens created by 3D printing is only twice the width of a human hair. Its makers claim the lens could lead to cameras the size of a grain of salt. It can be revolutionizing for a variety of applications including endoscopes for medical imaging, clandestine surveillance, robotics, and drone technology. A research team at the University of Stuttgart 3D printed a minuscule triple lens devices by combining three of the lenses into a 'pinhead' device. The paper was published on Nature Photonics on June 27, 2016. The ‘pinhead’ device is capable of razor sharp pictures and can...
