Researchers make first perovskite-based superlens for the infrared

Superlenses earned their superlative by being able to capture the “evanescent” light waves that blossom close to an illuminated surface and never travel far enough to be “seen” by a conventional lens. Superlenses hold enormous potential in a range of applications, depending upon the form of light they capture, but their use has been limited because most have been made from elaborate artificial constructs known as metamaterials. The unique optical properties of metamaterials, which include the ability to bend light backwards – a property known as negative refraction – arise from their structure rather than their chemical composition.
