Physik Instrumente (PI) has introduced the upgraded M-660 rotation stage and the E-725 three-channel motion controller for applications including tracking and inspection.

The new M-660.45 rotation stage has a 15mm construction height and a higher position resolution of 4urad, making accurate inspection tasks possible.

Designed for a maximum load of up to 1kg, it has a clear aperture of 35mm in diameter and compact combinations with linear stages are possible.

Below are some key features of the E-725 three-channel motion controller.

E-725 key features

  • Digital technology gives users access via software to numerous parameters
  • These optimise the settling time and linearity, or compensate for system inertia during fast scans
  • Optimisation of the dynamic positioning of specimen in the X, Y and Z directions, for applications such as tracking or atomic force microscopy
  • Uses USB and Ethernet
  • 32-bit processor with 225MHz and servo rate of 20kHz
  • Position signal with 24-bit resolution
  • ID chip that makes it possible to directly operate the nanopositioning system without prior adjustment at the factory

Physik Instrumente

PI is a global manufacturer of high precision positioning systems and products based on piezo technology. Used in markets as diverse as biotechnology, semiconductor, defence and astronomy, PI’s products work to improve the speed and precision of many cutting edge processes. Actuators, sensors and positioning systems with either sub-micron or nanometre level precision; many customised for the end user, are included in the product range.

With manufacturing and subsidiary offices around the world and a workforce of more than 500 PI provides direct local support where it is needed. Products range from component level piezo ceramic assemblies to six axis hexapod positioning robots. PI manufactures its own piezo ceramic material including multilayer devices that incorporate its patented ceramic insulation technology. Lead free ceramic technology is now also included in the company’s product range. With the flexibility and continuity of supply offered by having control of piezo ceramic production comes security and speed of delivery for customers who rely on or are looking to move into this area of technology. PI’s piezo ultrasonic and step drive motor technologies offer unique performance including self-locking capability, high force or high speed and non-magnetic and vacuum compatibility.
