Hybrid nanopositioning translation stage
Physik Instrumente has announced the M-511.HD hybrid nanopositioning translation stage, overcoming the limitations of conventional precision positioning systems.
PI (Physik Instrumente), manufacturer of nanopositioning and precision motion-control equipment for nanotechnology, photonics, semiconductor and life science applications, offers the M-511.HD hybrid nanopositioning translation stage The new hybrid system overcomes the limitations of conventional precision positioning systems by combing the well-known piezo-flexure-drive advantages of unlimited resolution and rapid response with the long travel ranges and high holding forces of a servo-motor / ballscrew arrangement

Precision linear stages are at affordable price
For precision automation uses, a motorized family of high-precision linear stages are combined with low-cost servo motor controller to form very affordable motion control systems.
Closed-loop scanning stages are flexure-guided
Closed-loop flexure-guided piezoelectric scanning stages provide a record travel range of 1000 microns and allow nanotechnology/precision microscopy probing of larger areas than before.
Typical Applications are Nano-Metrology, Surface Inspection, Microscopy, Laser Technology and Interferometry.
Features and Advantages are: Combines Advantages of Piezo-Flexure Drives and DC-Servo / Ballscrew Drives, Long Travel Ranges to 100 mm, 4 Nanometer Linear Encoder Resolution, Reliable Execution of Nanometer Level Increments, Millisecond Settling Time to Nanometer Accuracy, Active Compensation of Stick/Slip During Startup and Settling, Active Backlash Compensation, Excellent Velocity Control, 100 kg Load Capacity, High Holding Forces with Minimum Power Consumption.
The highly specialised C-702 Hybrid Nanopositioning Controller reads the stage position from an integrated, 4 nm resolution linear encoder and continuously actuates both the piezoelectric and servo motor drives in a way to provide the best possible overall performance.
Due to its high stiffness and instantaneous, sub-millisecond response, the integrated piezo flexure drive provides active stick/slip compensation during startup and settling.
It also improves velocity control and is the key to achieving consistent and repeatable nanometer level positioning increments.
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, without missing a single count.
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 RS-232; this interface makes it possible to operate and monitor the system over any TCP/IP-compatible network (intranet/internet). Request a free brochure from PI (Physik Instrumente) ...
