Scientists engineer a functional optical lens out of 2D materials

Scientists have constructed functional metalenses that are one-tenth to one-half the thickness of the wavelengths of light that they focus. Their metalenses, which were constructed out of layered 2D materials, were as thin as 190 nanometers -- less than 1/100,000ths of an inch thick.
