Superlens opens an optical window on the incredibly tiny

University of California Berkeley researchers have created a superlens that allows optical imaging at a resolution of about 60 nanometers. By contrast, current optical microscopes can only make out details down to about 400 nanometers.

The possible technological advances that could result include enormously enhanced data storage (the example given is a single DVD holding the entire contents of the Library of Congress) and, at the other end of the scale, and the even longer run, higher resolution imaging for distant objects, too.

The explanation of how it works (involving negative refraction and evanescent waves) is fascinating, too.
