High performance STM actively used in the leading edge surface science researches realizing the lowest base temperature and high magnetic field as commercially available systems. It is possible to customize a sample preparation system in line with a study goal. Fundamental to study superconductivity and low temperature physics.


  • Superconductivity phenomena under the ultra low temperature, observation of the electron energy structure
  • High resolution imaging for atoms and molecules
  • Observation of molecules vibration using IETS
  • Observation of spin responses using STS in high magnetic field.
  • Application for spin resonance measurements introducing high frequency
  • Observation of high resolution magnetic structure, spin polarization STM
