Poin

Non-Contact ModeIn this mode, the cantilever vibrates by itself at a resonant frequency and when the cantilever is approached to the sample, a vibration peak at the resonant frequency is shifted to a lower-frequency
due to an attractive force between the cantilever and sample. To
maintain this shift constant, frequency feedback is made.

 High resolution

Non-Contact mode

AC modeExample of imaging of Si steps
In Non-Contact mode, a higher-resolution image is obtained thanin AC mode.

To set the frequency of the cantilever beam to the resonant frequency any time, PLL (Phase Locked Loop) is used. The FM
detection method with PLL is a standard configuration of JEOL
SPMs, which is an unprecedented feature of JEOL SPMs.

In Non-Contact mode, an image is obtained without damaging thesample surface.

nVacuum evacuation

Optio

You can start evacuation by just pressing theStart button on the evacuation system controller.
A Pirani gauge and a Penning gauge can be
automatically switched, enabling the atmosphericpressure to high pressures to be accuratelymeasured. Also, you can stop the evacuation
system by one-button operation, from stopping toventing the pump automatically; thus eliminating
cumbersome valve open/close operations.

Imaging under the air

Imaging under the vacuum

Example of imaging of recrystallized glass
In the imaging under the air, a true topographic shape cannot be obtained due
to water adsorbed onto the sample surface. In the vacuum environment, thiswater desorbs, enabling crystalline facets to be observed.
High vacuum obtainable
using a button on thecontroller.

Sample heatingionOpt

The heating holder uses a thermally-stable graphite heater, enabling thesample to be heated up to 150°C in the air. By adding the vacuum evacuation system, the sample can be heated up to 500°C.

Temperature controller

You can exchange a sample while
maintaining the vacuum. Operationsof automatic sequences are madeby just pressing a button.

You can control the sample temperature with 0.1°C accuracy.

Example of imaging of macromolecule material
Phase transformations are observed at 124°C and 77°C. Also, thefield of view does not move during observation.

UsableionOpt

By using liquid nitrogen, you can easily cool the sample and observe it.
Anti Frost Shroud (AFS) reduces sample contamination caused by frost formation.
