Nanoscale Tapping AFM-IR Infrared Spectrometer
The Bruker Anasys nanoIR3-s brings together two nanoscale IR techniques: s-SNOM and AFM-IR, building on a legacy of award-winning technology.
- Two complementary nanoscale IR techniques – s-SNOM and AFM-IR
- 10nm resolution chemical and optical property mapping
- nano FTIR high performance broadband spectroscopy
- Full featured AFM, with unique nanoscale property mapping capabilities
Perform 10nm spatial resolution chemical imaging and spectroscopy. The example below shows a surface plasmon polariton (SPP) on a graphene wedge: s-SNOM phase and amplitude images, together with a 3D view of the phase image.
- Nano FTIR spectroscopy
- 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
The example below shows molecular vibrational information, acquired with ultrafast-broadband scattering SNOM spectroscopy. The laser interferogram (top) of Polytetrafluoroethylene (PTFE) shows coherent molecular vibration in the form of free-induction decay in time domain. The highlighted section is caused by the beating of symmetric and antisymmetric C-F modes, resulting in the frequency domain (bottom left). The bottom right shows data for a monolayer pNTP, demonstrating monolayer sensitivity.
Using POINTspectra lasers, you can perform spectroscopy and high resolution optical property mapping across a broad range of wavelengths:
- Using an AFM image, set the area to be measured
- Measure the spectroscopy and select a wavelength of interest
- Generate a high resolution optical property map
10nm spatial resolution images of amplitude and phase are rapidly measured from interferograms over a range of wavelengths. This enables 10nm resolution Tapping AFM-IR for complementary, unique IR spectroscopy.

Mechanical Property Mapping
With Lorentz Contact Resonance (LCR), materials are differentiated by their viscoelastic properties. This maps the distribution of components on a sample, and enables the probe to be positioned precisely for chemical and/or thermal analysis. Using Anasys’ unique self-heating ThermaLever probes, you can also measure temperature-dependent mechanical properties – useful for polymer blends, multi-layer films, composite materials and life sciences.
