Glass-Free Flat Lenses Offer New Medical Imaging

Jun-07-16 A new method of manufacturing flat, high-resolution lenses could offer significant improvements for an array of medical technologies.

The lenses differ from conventional versions in that instead of using glass, they are made out of nanoscale structures of titanium dioxide. The arrangement of the structures cause the light to travel in a way that mimics passing through a real lens, and can even resolve objects separated by distances that are less than a wavelength of light. However, the standout feature of the lens is its ability to work in the visible spectrum, which had not been possible before with a single flat element.
