New method for the measurement of nano-structured light fields: Researchers combine nano-optics and organic chemistry to measure complex light landscapes in the tight focus of a laser beam

Physicists and chemists have jointly succeeded in developing a so-called nano-tomographic technique which is able to detect the typically invisible properties of nano-structured fields in the focus of a lens. Such a method may help to establish nano-structured light landscapes as a tool for material machining, optical tweezers, or high-resolution imaging.
