Confocal Raman microscope for chemical identification and spatially resolved analysis.
Horiba · LabRAM HR Evolution confocal Raman microscope
What it does
A laser illuminates a small volume of the sample and the scattered light is analysed. A small fraction shifts in energy by amounts characteristic of molecular vibrations, giving a spectrum that acts as a fingerprint of the material. Because the optics are confocal, that fingerprint can be recorded point by point and assembled into a chemical map.
Key capabilities
- Identification of chemical phases and molecular structure
- Point spectra and area mapping across a surface
- No staining, labelling or destructive preparation
- Depth profiling through transparent samples
Applications
Materials · Chemistry · Nanoscience · Pharmaceutical · Environmental
Sample types
Solids, thin films, powders, particles, liquids and, in many cases, biological material without preparation.
