Systems for Scanning Probe Microscopy

Janis has standard designs available for Scanning Probe Microscopy (SPM), including Scanning Tunneling Microscopy (STM) and Atomic Force Microscopy (AFM), plus the capability of custom building any system to your specifications. No matter what your specific requirements, Janis can help.

Existing designs include:

Scanning Probe Microscopy (SPM)

• Helium-3 cryostat with top-loading sample located in ultra high vacuum environment -
  HE-3-TLSUHV-SPM
• Helium-3 cryostat with standard loading sample located in ultra high vacuum environment - 
  HE-3-SSUHV-SPM/ESR

Atomic Force Microscopy (AFM) and Scanning Tunneling Microscopy (STM)

• Helium-3 cryostat with bottom-loading sample locatedin ultra high vacuum environment -
  HE-3-BLSUHV-STM
• Ultra high vacuum compatible Dilution refrigerator - JDR-500-STM
• Custom designs (see below)

Cryostats for Low Temperature System for Attomic Force Microscopy (AFM)/Scanning Tunneling Microscopy (STM)

Shown to the right is a special helium dewar supplied to Seoul National University in South Korea. This unit was to be integrated into a UHV surface analysis system which includes instruments such as an AFM/STM probe. Featuring a modular design, this cryostat required the full complement of Janis' design and manufacturing capabilities—all at a cost far below our competitors.

Scanning Tunneling Microscopy (STM) Superconducting Magnet System with Optical Access

An 8 T split superconducting magnet system has been designed and built for a Scanning Tunneling Microscope with optical access to the microscope cooling stage. The microscope is top loaded into a UHV space that can be baked out to a temperature of 150 degrees Celsius without affecting the superconducting magnet or the rest of the cryostat. The system offers variable temperatures from below superfluid helium temperatures up to room temperature. Several variations are available on this basic design, enclosing bottom optical access, cryostats for Scanning Near Field Optical Microscopes, Atomic Force Microscopes, etc.  Please visit our UHV Compatible Superconducting Magnets web page.
