Sample is located on the flange centerline parallel to the flange. Modular tip holder design allows exchange of tips in vacuum. Reserve tips are conveniently stored on the microscope base plate. Damage to even several tips does not interrupt or delay STM operation. The STM base plate clamps rigidly in place for tip exchange, sample transfer and coarse tip positioning.
Vibration isolation is achieved by simply unclamping the base plate.
Beryllium-copper coil springs above stacked plates provide integral vibration isolation. No magnets are needed, so there are no magnetic fields to interfere with other instruments such as electron spectrometers. All piezo ceramic elements are field-replaceable in case of accidental mechanical or electrical damage. Optional sample sled for sample holders that are heated. Schematics and Source Code Complete electronic schematics are included with every unit.
