Researchers are the University of Stuttgart have demonstrated a technique using 3D-printing to fabricate multi-element lens systems on substrates as small as a human hair. The team printed a triplet lens directly on the end of an optical fiber and demonstrated high quality image transmission through the fiber for objects positioned as close as 3mm from the lens. The technology may be used to print lens elements directly on image sensors possibly eliminating the needs for optical components in micro vision systems.
The world’s smallest lens has been created using 3D printing, and it’s just twice the width of a human hair. Its makers claim the lens could lead to cameras the size of a grain of salt, revolutionising surgery, surveillance, robotics and drone technology. Researchers in Germany created a triplet […]
