Physik Instrumente (PI) has launched a fast, high-precision XY positioning system optimised for applications with inverse microscopes.

The new M-687 XY stage provides travel ranges of up to 100 x 75mm and its large clear apertures of up to 160 x 100mm can hold specimen holders as well as Z systems for specimen scanning.

The currently available models can be used for Olympus IX2 series and Nikon Eclipse TI series inverse microscopes.

The stage is driven by a Piline piezoceramic linear motor, which, in contrast to flanged stepper or DC motors with large leadscrew ducts, is integrated inside the stage and therefore does not require any additional installation space.

This facilitates the integration of the stage under the microscope and offers unhindered access to the specimen.

The Piline motors transmit the force directly to the moving platform, thus keeping the position stable, even when powered down.

As a result, they do not generate additional heat.

M-687 stages provide maximum closed-loop velocities of up to 250mm/sec.

Their settling behaviour is optimised; settling takes place within a few milliseconds.

A slow movement is also important for users; even if a distance of only a few micrometres per second is covered, the movement can still be observed under the microscope at 1,000-fold magnification.

By combining a Piline drive with a high-resolution position sensor, a stiff and high-precision stage has been designed that can reach positions repeatedly with submicron accuracy.

This is said to be useful for imaging methods such as tiling and stitching that are required for large specimens.

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.
