High Resolution Scanning Probe Microscope
Catalog/Part Number:: SPM-8100FM
Description
The new HR-SPM scanning probe microscope uses frequency detection.
This instrument is not only capable of ultra-high resolution observations in air or liquids, but for the first time enables observations of hydration/solvation layers at solid-liquid interfaces.
Existing SPMs (scanning probe microscopes) and AFMs (atomic force microscopes) generally use AM (amplitude modulation). In principle however, the FM (frequency modulation) measurement method enables higher imaging resolution.
Features of the HR-SPM
High Resolution
- Uses the FM method
- Noise in air and liquids is reduced to 1/20 that of existing methods.
- Achieves the performance level of a vacuum-type SPM, even in air and liquids.
- Enables measurement of the local structure at the solid-liquid interface.
