3.1 Micrometer Drives
3.1.1 Adjusting Differential Micrometer Drives
Turn the coarse adjustment clockwise until the top platform of the stage begins to
move. By use of the fine adjustment, sub-micron resolution is now achievable.

3.2 Piezo Actuators
Piezo actuators are used to give nanometric positioning of the top platform over a
range of 30 microns. They can also modulate the position of the platform at high
frequency.
On a piezo-actuated RollerBlock, position feedback may be incorporated to enhance
the repeatability and linearity of piezo motion.
The piezo actuators fitted to the RollerBlock should be used together with one of the
Thorlabs piezoelectric controllers – see the
relevant piezo controller handbook for
more details on the operation of piezo actuators.
