The system consists of a micromotion piezo-stage containing capacitance displacement gauge & high precision feedback controller. Positioning according to input command value can be made by feedback control with the capacitance gauge.
Piezo-servo positioner is constructed with non-friction linear guide driven by high speed piezo-electric actuator and capacitive displacement gauge (PS Sensor) for monitoring the stage position.
Specific hysterisis and creep characteristics of piezo-element are eliminated by feedback control system with PS Sensor which enables us high accuracy positioning easier.
Up to 4 channel sets can be extended in one in one housing.
