Combined Raman-AFM instruments enable improved sample analysis by investigating chemical and structural properties of materials at sub-micrometer scales.

Extend your understanding of the nanoscale

The Renishaw inVia Raman microscope is a highly flexible instrument that can be directly coupled to a wide range of AFMs and SPMs, including those made by Bruker Nano Surfaces, Nanonics Imaging Ltd, NT-MDT, JPK and Park. This enables you to choose an AFM suitable for the specific needs of your application area.

As well as providing co-localised Raman AFM measurements these combined systems can be used to collect Tip Enhanced Raman Spectroscopy (TERS) and to conduct near-field measurements (SNOM, NSOM). Combined Raman AFM measurements allow the investigating and characterisation of chemical and structural properties of materials at sub-micrometer scales.

What can a Renishaw Raman-AFM system do for you?

Raman with AFM

Raman data can be recorded and correlated with high spatial resolution topographic, electrical, thermal and near-field optical data provided by the AFM.

The Raman data was used to guide AFM experiments, enabling topographical, capacitance and conduction measurements in the regions of interest.

Tip Enhanced Raman Spectroscopy (TERS)

The spatial resolution of Raman spectroscopy is diffraction-limited to approximately half the wavelength of the incident laser light, because both the illuminating laser light and the Raman scattered light are collected in the optical far field. One way to achieve higher spatial resolution is to use a near field technique such as TERS. This technique involves using a plasmonic tip with a small apex to enhance the Raman signal at a very localised area of the sample. The Raman information from this small area can then be separated from the far field data potentially achieving resolutions better than 15 nm.

The Renishaw inVia Raman microscope has been used to collect TERS data in conjunction with a wide range of 3rd party instruments.
