Raman microscopy addresses different analytical questions: identify a material at a single point, map chemical composition across a sample, or resolve changes through a three-dimensional volume.
Bruker offers three Raman microscope platforms with different strengths in imaging speed, routine analysis, and measurement reproducibility: RAMANtouch, RAMANwalk and SENTERRA II.
Raman microscopy combines molecular information with spatial resolution. A Raman spectrum reveals chemical and structural characteristics; microscopy shows where those characteristics occur within the sample. Depending on the measurement task, the same technique can be used for point analysis, 2D chemical mapping, or 3D Raman imaging.
Different Raman measurements place different demands on acquisition. RAMANtouch, RAMANwalk and SENTERRA II address these with different approaches to imaging throughput, point scanning, automation and calibration.
Each platform supports confocal Raman analysis and chemical imaging. The main differences are how the Raman data are acquired, how imaging time is reduced, and how calibration and reproducibility are handled.
