Raman / AFM (Witec Alpha 300 RA+)

Description

The Alpha 300RA is a combines TrueSurface Raman imaging and AFM imaging in one instrument.

Raman

  • Laser wavelength: 532 nm up to ~ 55 mW.
  • Resolution: 1 cm-1 or ~ 3 cm-1 depending on the grating.
  • High sensitivity EM CCD.
  • 360nm lateral spatial resolution with 100x objective (0.9N.A.).
  • excellent confocality and depth resolution (<1 um).
  • 50x50 mm stage.
  • large Z range.
  • Reflected light.
  • image stitching.
  • Truesurface to compensate for sample topography while imaging the sample.

AFM

  • resolution X/Y ~3 nm and Z ~0.5 nm.
  • 80x80 um maximum area.
  • 5 um Z range.
  • AC (tapping) and contact mode.
  • force-distance curves.
  • TERS capable with appropriate tips.
