HORIBA XploRA MICRO-RAMAN

GENERAL INFORMATION | STANDARD OPERATING PROCEDURE

Location: Havemeyer 224

The Horiba XploRA Plus is a confocal Raman microscope that combines Raman spectroscopy with optical microscopy to provide chemical and structural information with high spatial resolution. This versatile imaging spectrometer uses inelastic scattering of monochromatic laser light to generate molecular fingerprints based on vibrational modes, enabling non-destructive identification and characterization of materials at the microscale. The confocal configuration allows for depth profiling and 3D chemical mapping by rejecting out-of-focus light, achieving spatial resolution down to approximately 1 μm laterally and 2 μm axially.

Specifications:

• 532 nm laser excitation (P ~ 0.01 to 17 mW)

• SWIFT and point-by-point Raman/PL mapping capability for rapid chemical imaging.

  • Horiba application example: Fast Raman Mapping of MoS2 flakes

• Automated grating calibration & selection

  • 600, 1200, 1800, and 2400 l/mm

• Automated polarization control

  • Vertical/horizontal/circularly polarized excitation.

  • Linear polarizers for the scattered light

It is commonly used for identifying unknown materials, studying phase distributions in composite materials, analyzing stress and strain in crystals, characterizing 2D materials and carbon allotropes (graphene, carbon nanotubes, diamond), examining pharmaceutical formulations, and investigating semiconductors and thin films. The system accommodates a wide range of sample types including solids, powders, films, and liquids.
