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. Comm. 7, 12045 (‘16). Doi:10.1038/ncomms12045

Eliminating the need for complex optical alignments
  • Patented adaptive beam steering and all reflective optics enables broad wavelength compatibility while eliminating realignment and refocusing at different wavelengths
  • Patented dynamic power control maintains optimal power and signal over broad range of sources, wavelengths and samples
  • Pre-mounted probes and motorized tip, sample and source alignment eliminates tedious steps in probe installation and re-optimization
