The translational movement of the Piezo actuator generates a minute rotational movement of the rotation plate.
An actuator with an operational range of 90µm is capable of a maximum angle range of 134 arc seconds.
The resolution of the system is dependent both on the length of the leverage arm (standard 137.51mm) and the resolution of the actuator.
A goniometer 410 or 408 mounted underneath is used for pre-adjustment.
The system is available in a high-vacuum configuration.
