Raman spectrometry is a powerful analytical technique for materials analysis with high spatial resolution. Our system is a research-grade model assuring high spectral quality for a broad spectrum of different applications from academic teaching to cutting edge research. Some of the distinct features of our system are:

  • Exceptional wavenumber accuracy with a high-precision rotary-encoder direct drive mechanism;
  • Low wavenumber measurement;
  • Auto-alignment of microscope laser introduction optics and Raman scattering light path;
  • Wavenumber calibration using an integrated Ne lamp;
  • Unique Dual Spatial Filter (DSF) for higher spatial resolution than conventional confocal optics;

Other specifications, as e.g. XYZ automatic stage with 100 nm resolution, four lenses on turret: 5x, 20x, 100x microscope objectives (VIS optimalised), 100x dedicated NIR objectives, and extensive mapping functions are available on Equipment page.
