Scanner
The Keysight 5500 is a tip-scanning system, in which the cantilever sits
on a scanner and is moved in raster fashion across the stationary sample.
The scanner (
) includes one or more elements made from
piezoceramic material. When an electric field is applied to the piezo
elements, they elongate or contract. The motion of the tip in the Z axis,
and raster scanning in the X and Y axes, are all achieved by applying
high voltages to the scanner’s piezo element(s).
Keysight’s multi-purpose scanner modules contain the piezo elements,
the socket for the nose assembly, mounting for the detector, and
interconnections. The scanners are considered “multi-purpose” because
nose assemblies can be switched in and out of the scanner for different
imaging modes or environments.

A-type Scanner Module
Keysight SPMs use two types of scanners: A and B. A-type scanners are
most typically used with the Keysight 5500 SPM. B-type scanners are
designed for Keysight SPM models that have a slightly different video
system and a differently shaped scanner holder. The B-type scanners are
equipped with a replaceable lens assembly so they can be used in the
5500 SPM.
A-type scanners that use a 980 nm IR wavelength laser diode are also
available for those using inverted microscopes or who have
