Teem Photonics has chosen PI’s P-611 Nanocube piezo stage – a high-precision, multi-axis piezo nanopositioning system – for its new uFab3D microfabrication system.

Typically used in microfluidics, cell biology and the manufacture of photonic crystal structures in micro-optics, the uFab3D system uses two-photon absorption to produce 3D polymer, protein, metal or other biomaterials’ microstructures.

The integration of PI’s versatile P-611 Nanocube into the uFab3D system enables precise alignment of laser and machining points, achieving resolution of 200nm at speeds of up to 100um/s, for homogenous, high-quality results.

Measuring 44mm, the easy-to-integrate, piezo actuator-driven P-611 Nanocube is suitable for travel ranges up to 100 x 100 x 100um and can achieve resolution of up to 0.2nm, with millisecond response times.

The basic, open-loop model is designed for applications where fast response and very high resolution are essential, but absolute positioning is not critical, while the closed-loop version is suited for applications requiring high accuracy and positioning precision.

The compact P-611 Nanocube systems are equipped with preloaded PICMA high-performance piezo actuators, integrated into a sophisticated, frictionless flexure guiding system.

Actuators, guides and sensors are maintenance free and not subject to wear, offering long lifetime and reliability.

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.
