Introduction to the LS-AFM

When fully assembled, the LS-AFM comprises four subunits. They are the control computer,
the Ebox, the stage, and the video optical microscope.

2.1 Computer

The control computer is a standard IBM/PC-type
computer with a Microsoft Windows operating sys-
tem. There are two programs required to operate
the LS-AFM: the AFM control software and the
software for the color video camera.

2.2 Stage

Samples are held and scanned on the AFM stage.
On the upright inside the stage is a linear translator
which moves both the light lever force sensor and
the piezoelectric scanner in a vertical direction. The
stage also includes a base plate fitted with precision
XY translators.
Optimal images are measured with the AFM stage if
it is in a vibration- and acoustic-free environment. If
necessary, a vibration and acoustic isolation system
should be used. Appendix A provides more information
on the best location for the AFM stage.
On the back cover of the stage is a modes connector.
Signals required for implementing additional modes
such as conductive AFM, STM, and EFM are provided.
Additional information on the cable configuration is
provided in Appendix A.
