MultiMode SPM Instruction Manual
Rev. B
Because each scanner exhibits its own unique piezo properties, each has its own parameter
fi
le.
When scanners are changed, the parameter
fi
le for the new scanner is changed along with it,
ensuring maximum accuracy at any scan size. Loading new parameter
fi
les requires only a few
seconds.
describes the range capabilities of each MultiMode SPM scanner.
Table 2.1a
MultiMode SPM Scanner Specifications
depicts the electrode con
fi
guration used on one type of scanner piezo tube. Electrodes
are oriented as shown when the MultiMode is viewed from the front. AC signals applied to
conductive areas of the tube create piezo movement along the three major axes. With the
Scan
angle
parameter in the control panel set to
0.00
, the fast-scan direction is in the direction of the X-
axis.
