Method for generation of focal points with arbitrarily oriented three-dimensional electromagnetic field for microscopy of nanoparticles, involves carrying out manipulation of polarization of light of nanoparticles

摘要

The method involves carrying out manipulation of the polarization of a light of nanoparticles, where a polarized input radiation beam (21) is divided. A linearly polarized partial radiation beam (41) and another polarized partial radiation beam are generated. An output radiation beam (111) is focused by using a microscope objective to a focus for illuminating a nanoparticle. An independent claim is also included for an apparatus for generation of focal points with arbitrarily oriented three-dimensional electromagnetic field for microscopy of nanoparticles.
