Tech Center 177 (Poly campus)
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
