  • Watching original webinar recording (~50 min) is highly recommended rather than looking at this PDF.

    On the original recording you will be able to see unique videos of TERS, SNOM and AFM-Raman experiments.

    In this webinar we will present exciting recent applications and instrumentation developments in the field of AFM integration with optics aimed for super-resolution optical imaging. The material presented will include:

    • Tip Enhanced Raman Scattering (TERS, “nano-Raman”)
      • ~10 nm resolution hyper-spectral chemical and structural imaging of: DNA, graphene, semiconductors, polymers, molecular monolayers, lipid membranes, various protein structures etc.
      • Reliable probes for reproducible nano-Raman
      • Instrument optimization for easy setting up of the TERS experiment and fast mapping
      • Universal optical access to the AFM probe: from Top, Bottom and Side; UV – VIS – IR wavelength ranges.
    • Scanning Near-field optical microscopy (SNOM)
      • Aperture and apertureless (s-SNOM) techniques for optical resolution down to 50 nm and less
      • Plasmonic structures, photonic crystals and waveguides, lasers, optical fibers, focusing elements etc.
      • New generation of SNOM probes and new measuring modes
    • Co-localized AFM and optical imaging (diffraction limited)
      • Co-localized AFM-Raman imaging; including Hybrid AFM measuring mode for quantitative nano-mechanics
      • AFM with confocal microscopy & fluorescence lifetime (FLIM) microsopy

    We will show the advantages and limitations of each technique when applied to various samples. Review sample and probe preparation issues and give an overview of how your specific research can benefit from each technique.
