Raman Spectroscopy

Overview: Integrated Raman Spectroscopy in Tabletop SEM

This system represents a powerful Correlative Light and Electron Microscopy (CLEM) approach. By integrating a Raman spectrometer directly into a tabletop Scanning Electron Microscope (SEM), laboratories can achieve high-resolution imaging and sophisticated chemical analysis simultaneously on the same sample area.

How It Works

    1. SEM: The electron beam provides high-resolution structural imaging.

    2. Raman: A laser is shone onto the sample; the system recovers inelastically scattered photons.

    3. Result: The spectrum reveals molecular structure and material composition.

Key Benefits & Advantages

1. Enhanced Analytical Capabilities

  • Non-Destructive: Analysis does not damage the sample, preserving it for future testing.

  • Minimal Preparation: Provides chemical data without complex sample prep.

  • Versatility: Works on any non-metallic material with molecular vibrations.

  • Precision: Combines the excellent spatial resolution of SEM with sub-10µm Raman precision.

2. Optimized for Small Laboratories

  • Compact Footprint: What previously required multiple large instruments now fits in a single desktop unit.

  • Cost-Efficiency: Consolidates imaging and analysis into one investment, reducing equipment and maintenance costs.

  • Workflow Efficiency: Eliminates the need to move samples between instruments, preventing contamination and registration errors.
