Ultrahigh Vacuum, Ultra Low Temperature and High Magnetic Field Scanning Probe Microscope USM-1300

PDF Brochures
This system is designed for stable STM at ultra low temperature.
This system is suitable for the spectroscopy on single molecule (IETS) and useful for the observation of various phenomenon on surface at low temperature. Moreover you can apply high magnetic field during STM measurement.
This STM is available for spin analysis of magnetic material (Spin- polarized STM). UHV ULT High Magnetic Fields USM-1300 picture
