Observing 2D Materials at the Nanoscale with the nanoIR3-s Broadband

The nanoIR3-s Broadband from Bruker is the world’s most sophisticated s-SNOM-based nanoscale FTIR spectroscopy system. The system offers the widest possible spectral range (from 670 to 4000 cm−1) with high-resolution nano-optical and nanochemical imaging features.

The platform integrates the industry-leading Anasys nanoIR3-s system with the newest OPO/DFG femtosecond laser technology, thus delivering unrivaled levels of performance, flexibility, and integration.

Broadband Features of nanoIR3-s:

  • FTIR spectroscopy and imaging with the maximum possible performance for 2D/graphene materials
  • Widest possible spectral range for high-resolution nanochemical imaging and spectroscopy
  • Material property mapping at the nanoscale and sample environmental control possibilities

Nanoscale FTIR Spectroscopy for 2D Materials

Scientists can now leverage the exclusive capabilities of the nanoIR3-s Broadband system to come up with new discoveries in a wide array of research areas such as catalysis-based applications, biological samples, polymeric materials, and 2D materials in spectral regions not accessed earlier.

Complementary High-Resolution Imaging

Superior-quality, high-resolution nano-optical images can be produced for characterizing a broad variety of optical phenomena, like surface phonon polaritons and graphene plasmonics in hexagonal boron nitride (hBN), and chemical imaging of biological and other organic samples.
