Product Spotlight January: Ring Actuators R/RA


ring actuators by piezosystem jena

Ring Actuator of the RA Series

Ring actuators are often used in optical applications such as laser beam steering, fiber alignment or AFM scanning. In order to achieve optimal positioning results, these actuators have to fulfill a number of tough requirements. Especially stiffness and guidance accuracy are important criteria when it comes to operating the actuators in the sub-nm range and with high dynamics. The ring actuator series R/RA was developed and designed by piezosystem jena to meet the high requirements of these applications.

The R/RA series ring actuators offers motion of up to 50 µm. Their apertures of up to 14 mm are especially useful for optical applications because they allow for light to travel through. Stiffness is up to 330 N/µm which enables the user to operate the actuators with extremely high dynamics. This is an especially beneficial characteristic for a ring actuator, since they are often used in laser resonators.

Piezo ring actuators by piezosystem jena are available in housed (RA) and un-housed (R) versions. The housed RA models also offer an additional increase in guidance accuracy thanks to its sophisticated casing design. The RA ring actuators are also preloaded which enables them to achieve even higher dynamics. Customized solutions according to individual customer requirements are available for all models. Our engineers will advise you here.

There are several option for piezo amplifiers in order to optimally control the ring actuators. Our sales and technical support team will support you to find the best option for your application. Contact sales(at)piezojena.com, call +49(0)364166880 or use our contact form.
