Series R ring actuators consist of a large number of contacted ceramic discs. Compared with a tube actuator, the ring actuator reaches a higher stiffness and the expansion is twice as high.
Series R piezo actuators are without casing, and without a pre-load. They are only connected at the ceramic top and ground plate. These ring actuators (without a pre-load) should not be used in dynamic applications.
Series R actuators are for open-loop systems only.
Please ask for a screwing top plate for easy mounting of mirrors.
