UHV LT-SPM and Raman System USM1400-TERS

UHV LT-SPM and Raman System USM1400-TERS
  • High resolution STM
  • Sample Scanning and fixed tip for static optical focus
  • Tunneling Spectroscopy (STS, IETS)
  • Single molecule spectroscopy
  • Confocal Raman micro spectroscopy option
  • Tip Enhanced Raman Spectroscopy (TERS)
  • Single molecule spectroscopy


Scan Range at RT

( X / Y / Z)  =  ( 5 / 5 / 0.4 ) μm

Scan Range at 4K

( X / Y / Z)  =  ( 1 / 1 / 0.15 ) μm

Coarse Range

2mm in X and Y


‘open deck’ design leaving space for close-up optics with high numerical aperture

Space for customised in-situ optical elements – ‘optical bench’ on cold deck

Inverted design with cryostat underneath the SPM stage

Combining the best of two worlds: LHe bath cryostat plus He flow heat exchanger

Ideal for low and variable temperature ~3K to 20K

Up to 80K with counter heating. LN2 operation possible (80K to RT)

Tip Enhanced Raman Spectroscopy

Integrated solution with TII Nanofinder FLEX Raman Spectrometer (ambient)

in UHV focussing lens (aspherical (NA 0.3); on XYZ piezo positioner for optimal focus).
