Ultra Swift - Graphene on Silicon

Ultra Fast Raman Imaging for detailed Raman maps

SWIFT™ ultra-fast Raman imaging  allows detailed Raman maps can now be acquired on second/minute timescales with integration times down to 1ms and below.  SWIFT™ retains the true confocal performance of the HORIBA Scientific Raman systems, thus ensuring optimised spatial resolution for analysis of small particles and thin layers

Segment: Scientific
Manufacturing Company: HORIBA France SAS

Second generation SWIFT ultra-fast Raman imaging, showing real time hyperspectral Raman image acquisition on a structured semiconductor device, with 40,200 spectra acquired in less than 50 seconds.

Fast Raman imaging offers many advantages to the user:

  • Acquisition times reduced by orders of magnitude without compromise in image quality.
  • Macro areas (centimeters) can now be analysed with micro resolution.
  • High definition megapixel Raman images are now possible in a single fast Raman map, providing both a broad overview and detailed high resolution work in a single experiment.
  • Data rich 3D confocal volume images can be acquired in realistic timescales, allowing a sample’s internal structure to be interrogated.
  • Time resolved Raman imaging – with a full image acquired in just a few seconds, chemical reactions such as polymer curing occuring on minute/hour timescales can now be imaged.

SWIFT™ is suitable for use with all lasers from UV through to near infra-red. It is compatible with all HORIBA Scientific systems, either at time of purchase, or as a retro-fittable upgrade (additional or replacement parts may be required).
