Scientists have created the world’s thinnest lens, 1/2000 the thickness of a human hair, opening the door to flexible computer displays and a revolution in miniature cameras. Dr Yuerui (Larry) Lu from The Australian National University (ANU) said the discovery hinged on the remarkable potential of the molybdenum disulphide crystal. “This type of material is the perfect candidate for future flexible displays,” said Dr Lu. “We will also be able to use arrays of micro lenses to mimic the compound eyes of insects.”
The 6.3-nanometre lens outshines previous ultra-thin flat lenses, made from 50-nanometre thick gold nano-bar arrays, known as a metamaterial.
“Molybdenum disulphide is an amazing crystal,” s...
