What Raman images can reveal

What Raman images can tell you

We can use Raman spectroscopy to obtain chemical and structural information that helps us understand more about the materials we analyse. This information can be collected from an array of points on—or in—a sample, and visually represented as images (1D, 2D or 3D) depicting any of the parameters which can be revealed using Raman.

Spatial analysis of material

You can determine:

  • if a specific material or species is present
  • if any unknown materials are present in the sample
  • the variation in a parameter of a material, such as crystallinity or stress state
  • the distribution of the material or species
  • the size of any particles or domains
  • the thickness and composition of layered materials, such as polymer laminates, from micrometres to millimetres thick
  • the relative amounts of materials or species

Revealing the science from the image

Images are a powerful way to convey the science of the sample. The brightness, contrast and colour of the image can all be used to emphasise key information. By overlaying or combining individual images, you can display multiple species or parameters at the same time.

Quantitative data can also be extracted from images, such as particle statistics (number of particles, average size, etc.). These provide objective metrics from which image information can be confidently quantified, making comparison simple.
