Features

Crossed Roller Bearing Design

To ensure accurate linear travel, the stages use thermally matched, hardened-steel, crossed-roller bearings and high-precision reference surfaces. The result is a line of translation stages that offers an angular deviation of < 150 µrad in any axis and straight-line accuracy better than 3 microns as well as high load capacity and stiffness. Crossed Roller Bearings offer all of the advantages of ball bearings with higher load capacity and higher stiffness. This is a consequence of replacing the point contact of a ball with the line contact of a roller. Due to the averaging characteristics of line contacts, angular and linear deviations are generally below those found in ball bearings.

< 30 nm Resolution

Our Picomotor actuators have a step size of < 30 nm, allowing for very small, controlled movements of the crossed-roller bearing linear stage.  The step size is dependent on the load with higher loads allowing for smaller minimum incremental motion.

Easy-to-Use, Flexible Controllers and Drivers

Our Open-Loop Picomotor controllers and drivers are modular. You can daisy-chain up to 31 drivers together with four channels each, so you can have a network of up to 124 standard Picomotor actuators. You have two interface options with the controller system: hand pad or computer, both providing plug-and-play use. Alternatively, you may choose to use our TTL/Analog Picomotor driver.

Set-and-Forget Long-Term Stability

The Picomotor actuator moves when voltage is applied to the piezo, changing its length and in turn moving the jaws which turn the screw. When no power is applied, the actuator does not move. You can feel confident that your linear translation stage will stay put, even when you power down your system.
