Perovskite IR Superlens Set Up (IMAGE) DOE/Lawrence Berkeley National Laboratory Caption Experimental setup shows an IR free-electron laser light source and perovskite superlens consisting of bismuth ferrite (BiFeO3) and strontium titanate (SrTiO3) layers. Imaged objects are strontium ruthenate patterns (orange) on a SrTiO3 substrate. The near-field probe is shown in blue and the evanescent waves in red.
