LineScan

HORIBA Scientific was the first to introduce the line scanning mode which significantly reduces acquisition times for Raman images by simultaneously recording many spectra along a line.  Two dimensional images are obtained faster than conventional point-by-point mapping.

Unlike other hybrid line focus techniques which can compromise on confocality and spatial resolution, the LineScan offers improved confocal performance ensuring that true microscopic spatial resolution is retained, whilst acquisition times are reduced.

The LineScan module offers:

  • High speed Raman image acquisition
  • Lower laser power densities for photo-sensitive samples
  • Full spectral information available for data processing
  • True uniformity of illumination
