4.3 Piezo Actuators
Piezo actuators are used to give nanometric positioning of the platform over a range
of 20 to 100 microns – see Table 3.2. They can also modulate the position of the
platform at high frequency.
On a piezo-actuated stage, position feedback may be incorporated to enhance the
repeatability and linearity of piezo motion.
The piezo-actuated stage should be used together with one of the Thorlabs
piezoelectric controllers – see the handbook supplied with the relevant piezoelectric
controller for more information.
