The vacuum versions of the Picomotor actuators can be used in vacuum (10^-6 Torr) environments and the ultra-high vacuum versions of the Picomotor actuators can be used in UHV (10^-9 Torr) environments as well as VUV/EUV applications.

Our Picomotor actuators have a step size of less than 30 nm per step, allowing for very small, controlled movements. Note that the step size for open-loop picomotors varies from step to step and between forward and backward directions, and is directly related to payload – hence, position feedback should be provided by an external signal when operating an open-loop picomotor. For vacuum applications requiring absolute position calibration and high repeatability, consider a Vacuum Compatible Closed-Loop Picomotor actuator.

All of our vacuum compatible and ultra-high vacuum compatible Picomotor actuators come with short, Teflon-coated leads so you can make connections to your vacuum-chamber feedthrough. If, however, you are working with X-rays or other high-radiation applications, we offer versions with Kapton-coated wire extensions.

We offer both Open-Loop Picomotor controllers and drivers as well as Closed-Loop Picomotor controllers and drivers. You have two interface options with the controller system: hand pad or computer, both providing plug-and-play use. Alternatively for open-loop actuators, you may choose to use our TTL/Analog Picomotor driver.
