SPM, STM, AFM, Scanning Probe Microscope, Cryostat for Spectrophotometer- UNISOKU

USM-1100 series makes it possible to observe the sample surface in UHV at room temperature by STM and/or AFM.

• STM system: USM-1100S
• AFM system: USM-1100A
• STM / AFM system: USM-1100SA

USM-1200 series makes it possible to observe the sample surface in UHV at ultra-low temperature by STM and/or AFM.

• STM system: USM-1200S
• AFM system: USM-1200A
• STM / AFM system: USM-1200SA

USM-1300 series makes it possible to observe the sample surface at low temperature in UHV by STM or AFM and analyze surface electronic properties using various methods.

The system is adopted newly designed cryostat of which liquid helium reservoir is built under the SPM stage. This configuration of the cryostat realizes the features, such as high stability of temperature, long holding time of LHe, ease of operation, and the facility for the compact design of total system.

Surface observation with high resolution is possible only in the high vacuum condition. The high end technology of UNISOKU is condensed into this compact designed system which realize many functions of operations and applications to wide variety of sample materials.

New XHV, Ultra-Low-Temperature, and High-Magnetic-Field SPM(NC-AFM and STM mode).
Atomic resolution performance by Self-sensitive NC-AFM mode.
New high performance preamplifier for NC-AFM.
SPM stage is made by nonmagnetic titanium.
