Ultrafast-broadband scattering SNOM spectroscopy probing molecular vibrational information. Laser interferogram of Polytetrafluoroethylene (PTFE) shows coherent molecular vibration in the form of free-induction decay in time domain (top). The highlighted feature in sample interferogram is due to the beating of symmetric and antisymmetric mode of C-F modes in the resulting the frequency domain (bottom left). Monolayer sensitivity of nano-FTIR is demonstrated on a monolayer pNTP (bottom right). Data courtesy of Prof. Markus Raschke, University of Colorado, Boulder, US

Combine S-SNOM and AFM-IR  to create remarkable new data

Complementary AFM-IR and Scattering SNOM images reveal, for the first time, the microscale origins of optical chirality on plasmonics structures. By accessing both the radiative (s-SNOM) and non-radiative (AFM-IR) information on plasmonics structures, unique and complementary plasmonic properties can be obtained. Khanikaev et al., Nat.

"The nanoIR2-s is a perfect tool for a multi-user center with a combination of Soft Matter and Condensed Matter research"
"We chose the nanoIR2-s for the Soleil Synchrotron since it is a perfect tool for a multi-user center like ours where we undertake research into a wide range of materials. The nanoIR2-s uniquely combines the complementary techniques of AFM-IR and s-SNOM. AFM-IR provides true, model-free nanoscale IR spectroscopy and is ideal for research on materials such as life sciences, polymer and organics. Additionally s-SNOM is a complementary technique that provides sub-20nm complex optical property imaging and is most suitable for materials like graphene, 2D materials and photonics.”
