P-621.1U • P-625.1U PIHera Linear Precision Positioner

Vacuum Compatible and with Variable Travel Ranges and Axis Configuration

Travel ranges 100 to 500 µm (600 µm open loop)
Resolution to 0.2 nm
Linearity error ≤0.03 %
XY combination possible
UHV compatible to 10^-9 hPa

Rapid scanning motion of a P-621.1CD (specified rise time: 5 ms) with a digital controller with 16-bit sensor resolution and DDL option. The digital dynamic linearization reduces the tracking error during scanning to <20 nm. The improvement over a standard PID controller is up to 3 orders of magnitude and increases with the frequency.

P-62x.1U, dimensions in mm. Note that a comma is used in the drawings instead of a decimal point.

Suitable for sophisticated vacuum applications

All components used in the piezo systems are excellently suited for use in vacuum. No lubricant or grease is necessary for operating. Polymer-free piezo systems allow particularly low outgas rates.

Outstanding lifetime due to PICMA^® piezo actuators

The PICMA^® piezo actuators are all-ceramic insulated. This protects them against humidity and failure resulting from an increase in leakage current. PICMA^® actuators offer an up to ten times longer lifetime than conventional polymer-insulated actuators. 100 billion cycles without a single failure are proven.

Subnanometer resolution with capacitive sensors

Capacitive sensors measure with subnanometer resolution without contacting. They guarantee excellent linearity of motion, long-term stability, and a bandwidth in the kHz range.

High guiding accuracy due to zero-play flexure guides

Flexure guides are free of maintenance, friction, and wear, and do not require lubrication. Their stiffness allows high load capacity and they are insensitive to shock and vibration. They work in a wide temperature range.

Maximum accuracy due to direct position measuring

Motion is measured directly at the motion platform without any influence from the drive or guide elements. This allows optimal repeatability, outstanding stability, and stiff, fast-responding control.

The resolution of the system is limited only by the noise of the amplifier and the measuring technology because PI piezo nanopositioning systems are free of friction.

All specifications based on room temperature (22 °C ±3 °C).
