Applications of scattering Scanning Near-Field Optical Microscopy | Dr. Artem Danilov

Optical Seminar at The Department of Physics & Engineering, ITMO | 4 Jun 2021 Timecodes are below the abstract. Dr. Artem Danilov, Attocube Systems AG, neaspec product line Title: "Applications of scattering Scanning Near-Field Optical Microscopy and Spectroscopy" Abstract: Scanning Near-Field Optical Microscopy (SNOM) breaks the diffraction-related limitation for the optical analysis methods. Recent advancements in scattering SNOM development provide tools to perform artifact-free nanoscale optical characterization with wavelengths from VIS and IR to THz with a broad range of applications in various research fields. This talk with introduce the technology of nanoFTIR and show examples of technology utilization.
