Combined Raman systems

You can couple a Renishaw inVia™ confocal Raman microscope or Virsa™ Raman analyser with other analytical instruments to gain correlative imaging capabilities. Our engineers have successfully integrated Renishaw Raman spectrometers with a wide range of analytical techniques. You can thus combine Raman spectroscopy data with information from other analysis methods including:

  • Scanning electron microscopy (SEM)
  • Atomic force microscopy (AFM)
  • Tip-enhanced Raman spectroscopy (TERS)
  • Brightfield, darkfield and polarised microscopy
  • Transmitted light microscopy
  • Fluorescence microscopy
  • Photoluminescence (PL)
  • Second-harmonic generation (SHG)
  • Fluorescence lifetime imaging microscopy (FLIM)
  • Time-correlated single photon counting (TCSPC)
  • Infrared (IR) thermography
  • Photocurrent mapping
  • Nanoindentation
  • Rayleigh mapping

For an efficient workflow, you can analyse your sample with two or more characterisation techniques on a single integrated instrument. With Renishaw's correlative microscopy solutions, you can be confident that you are analysing the same point with more than one technique. Explore some of our combined Raman systems below.

Second-harmonic generation (SHG)

You can configure an inVia microscope to perform second-harmonic generation (SHG) imaging. SHG is a non-linear optical process where two photons simultaneously interact within a material to produce a single photon with double the frequency.

SHG only occurs in materials that do not have inversion symmetry. The intensity of the frequency-doubled photons, and their directionality is dependent on the strength, distribution and directionality of the induced dipoles within the focal volume. By analysing these photons, we are probing the second-order electric susceptibility tensor of a material. This enables the characterisation of crystallographic, electronic and magnetic properties of the material.

Polarised SHG image of MoS2

Polarised SHG image of MoS2. The image shows the variation in SHG intensity which is a function of crystal orientation. We used StreamHR™ Rapide imaging technology to collect SHG data in just 9 minutes using step sizes of 200 nm.

SHG is a fast technique that provides complementary information to Raman spectroscopy. It is important for investigating 2D materials for nano-optics and optoelectronics applications, as well as biological imaging. Another common use of SHG is to identify regions of interest for detailed Raman analysis. For example, SHG can identify regions rich in fibrillar collagen in biological tissues.
