• A team of physicists at ETH Zurich has created a tiny metalens that can half the wavelength of incident light.
• They have achieved this using a special metal-oxide lens material called lithium niobate and through nanoscale pattern, stamped into the material.
• Such metalenses could be used as a security feature on banknotes or in the fabrication of ultra-thin elements for cameras.
