Thin silver sheet makes superlens

Abstract:
An ordinary lens can focus light to about half the light's wavelength. Visible lightwaves range from 400 to 700 nanometers, and ultraviolet lightwaves range from 10 to 400 nanometers.

Researchers from the University Of California at Berkeley have fashioned a superlens from a thin sheet of silver that resolves images as small as 60 nanometers using 365-nanometer light.
