Correlative Raman Imaging of Polymeric Materials
Confocal Raman microscopy is a promising technique for highresolution, non-destructive and label-free analysis of polymers in two or three dimensions. It can easily be combined with other imaging techniques such as AFM or SNOM.

The Raman principle
The Raman effect is based on inelastic scattering of excitation light by the molecules of gaseous, liquid or solid materials. The interaction of a molecule with photons causes vibrations of its chemical bonds, leading to specific energy shifts in the scattered light that can be identified in its Raman spectrum.
