The M-683.2V4 translation stage, which Physik Instrumente (PI) claims is one of the flattest micro-translation stages on the market, is now available for use in vacuum environments to 10-6mbar.

An encoder resolution of 0.1um over 50mm travel makes the M-683.2V4 suitable for tasks requiring a high degree of precision.

For better guiding accuracy, the M-683 positioner uses two crossed-roller bearings that are mounted on precision-ground aluminium profiles.

They are designed for loads up to 5kg.

Its piezoceramic U-164 PILine linear motors have high holding forces that are greater than the drive forces, even when powered down.

This means they generate no heat when at rest, nor is there any positional jitter with active closed-loop control, as may occur with conventional motors.

The PILine piezomotor technology developed by PI requires neither spindle nor gear.

The direct drive is integrated in the stage and gives it its high velocity of up to several hundred millimetres per second.

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.
