Superlens Opens Nano-Doors

Facebook X LinkedIn Email
BERKELEY, April 28 -- A superlens that can overcome a limitation that has constrained the resolution of optical images is being created at the University of California, Berkeley (UC Berkeley). At present, optical microscopes can only make out details down to a tenth the diameter of a red blood cell, or about 400 nanometers. Using a thin film of silver as the lens and ultraviolet (UV) light, Berkeley researchers recorded the images of an array of nanowires and the word "NANO" onto an organic polymer at a resolution of about 60 nanometers. The breakthrough (reported in the April 22 issue of the...Read full article
