Long range for PZT steering mirror
Polytec PI, NanoPositioning Group, has released what it claims to be the world's longest-range high-speed PZT-driven two-axis mirror scanner.
The highly specialised C-702 hybrid controller reads the stage position from an integrated, 2nm precison linear encoder and continuously actuates both the piezoelectric and servomotor drives in a way to provide the best possible overall performance.
Due to their instantaneous, submillisecond response, the integrated piezo actuators provide active stick/slip compensation during startup and settling.
They also improve velocity control and positioning performance when nanometre level steps need to be executed.
The C-702 hybrid controller is equipped with a novel high-speed encoder interface and can handle encoder count rates of 100 million pulses per second.
Thanks to its real-time operating system, the intricacies of the hybrid drive are completely transparent to the user.
Interface to the host computer is via TCP/IP or RS232; this interface makes it possible to operate and monitor the system over any TCP/IP-compatible network (intranet/Internet).
A 100mm hybrid translation stage is also available. Request a free brochure from PI (Physik Instrumente) ...
