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.
