Using a single molecule as a local field sensor, we precisely sample the absolute field strength and temporal evolution of tip-confined nearfield transients in a lightware-driven scanning tunnelling microscope. To develop a comprehensive understanding of the extracted atomic scale nearfield, we simulated the far-to-near-field transfer with classical electrodynamics and include time-dependent density functional theory to validate our calibration and conclusions.
