DuoScan™ Macro and Sub-Micron Raman Mapping

The innovative DuoScan™ Imaging system extends the imaging capabilities of HORIBA Scientific’s Raman instruments from sub-micron to macro-scale mapping. Generating confocal images becomes faster, easier and more flexible, from the deep UV to the IR.

The DuoScan™ Imaging technology available on the instruments of the LabRAM Series introduces a new imaging mode, based on a combination of scanning mirrors that scan the laser beam across a pattern chosen by the operator: a line for linear profiles, or an area for two-dimensional mapping.  It can be used to generate a rastored "macro laser spot" for large area mapping; alternatively, its 50 nm step piezo controllers are ideally suited for Raman mapping of sub-micron features.


  • Fast and uniform scanning over both small and large areas
  • Map area in step-by-step mode: 30 µm x 30 µm with a 50X microscope objective
  • Compatible with true confocal microscopes for high axial resolution
  • Operating spectral range from 220 nm to 1600 nm
  • Scanning step sizes down to 50nm
