  • Very Long Measurement Time
  • Integrated TRIBUS Head
  • Temperature: 10 K to 420 K

The new INFINITY UHV SPM is a pulse tube cooler based low-temperature SPM for high-resolution STM, QPlus®-AFM, and spectroscopy experiments in a temperature range between < 10 K and 420 K. The cooler with very long service intervals belongs to the next generation of cryostats that are independent of cryogenic liquids. The instrument can stay cold for several months and thus, serves as an ideal platform for long term and un-interrupted high resolution measurements.

The new INFINITY UHV SPM is a low-temperature SPM for high-resolution STM, QPlus®-AFM, and spectroscopy experiments. A pulse tube cooler is employed to cool the UHV SPM in a new, unique design. This renewable cryostat, which has no moving parts in the cold head and very long service intervals, belongs to the next generation of cryostats that are independent of cryogenic liquids. The handling of liquid helium or liquid nitrogen is no longer necessary, thus making instrument use simpler and safer. The instrument can stay cold for several months without the need for any maintenance of the cryostat.

For optimum mechanical decoupling, the sensitive SPM is mounted in a dedicated UHV chamber with ports for sample transfer, optical access, and evaporators, and the noisy pulse tube cooler is located in a separate high vacuum chamber. In addition, the SPM head is mechanically decoupled by a spring suspension with eddy current damping. This unique two-chamber design with incorporated mechanical decoupling units, sophisticated thermal connections, and dedicated acoustic noise cancellation is the key to pm-stability in a temperature range from 10 K to 420 K.

Benefits and Properties:

  • Independent from liquid helium and liquid nitrogen, only power and water are required to cool the instrument.
  • High operating safety: no need for handling of cryogenic liquids.
  • User-friendly: no filling/refilling of cryostats and no blockages - just press a button to cool the instrument to 10 K.
  • Quiet working environment.
  • Long (“infinite”) measurement time.
