Nanoscale Infrared Spectrometer

Anasys nanoIR3-s

Highest performance s-SNOM and AFM imaging


Anasys nanoIR3-s

Bruker's Anasys nanoIR3-s system combines scattering scanning near-field optical microscopy (s-SNOM) and nanoscale IR spectroscopy (AFM-IR) with an integrated atomic force microscope (AFM), all in a single platform. Building upon the legacy of Anasys technology leadership in AFM-based nano-optical characterization, nanoIR3-s provides nanoscale IR spectroscopy, chemical imaging, and optical property mapping with 10-nanometer spatial resolution demonstrated on 2D material samples. The system also enables AFM topographic imaging and material property mapping with nanometer-scale resolution, making it an ideal instrument for correlative studies across a wide range of material science applications.

High-Resolution Property Mapping

High-Resolution Property Mapping: Cross-section through the graphene flake shows sub 10nm resolution optical property imaging.

Highest Performance Nano FTIR Spectroscopy

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.

Only nanoIR3-s provides:

  • Highest performance nano FTIR spectroscopy
  • Highest performance IR SNOM spectroscopy with the most advanced nanoIR laser source available
  • nano FTIR spectroscopy with integrated DFG, continuum based laser source Broadband synchrotron light source integration
  • Multi-chip QCL laser source for spectroscopy and chemical imaging

POINTspectra Technology

POINTspectra lasers enable both spectroscopy and high-resolution optical property mapping across a broad range of wavelengths. With nanoIR3-s it is a simple task to generate correlated data:

  1. Select feature to be measured in the AFM image
  2. Measure spectroscopy of sample and select wavelength of interest
  3. Create high-resolution optical property map
10nm spatial resolution images of amplitude and phase are rapidly measured from interferograms over a range of wavelengths Enables 10nm resolution Tapping AFM-IR for complementary, unique IR spectroscopy.
