Researchers create world's thinnest lens
A team of Australian National University researchers has created the world's thinnest lens measuring at 6.3 nanometres, which is around 2,000 times thinner than human hair, and with a radius of 10 microns. The previous thinnest lens was measured at 50 nanometres. For this, researchers used nine 0.7-nanometre thick atomic layers of a chemical compound called Molybdenum disulfide.
