Imaging System Fits Inside a Syringe Needle

For the first time, physicists have used 3-D printing to make a complex lens no bigger than a grain of salt. With that, which can correct the aberration of color wavelengths into the same focal plane, researchers at the University of Stuttgart fashioned a camera of 125 micrometers (diameter and height) able to fit on the end of a catheter, passing through a standard syringe needle.
