Micro-Venus Structures (IMAGE) Optica Caption This image, taken by a scanning electron microscope, shows 16 micro-Venus structures that were produced simultaneously by a 16-beam two-photon polymerization system. The width of the entire array is less than the diameter of a typical human hair. The 16 structures were produced in approximately 45 seconds.
