Theta-2-Theta Dual rotation system consists of two rotation stages arranged in such a way that axes of rotation of both axes are concentric. Both axes have preloaded bearings and motorized worm gear mechanism for wobble-free rotation and positioning.
Both inner and outer axes can rotate 360 degrees independently. Both stages have metric tapped holes for mounting components and sub-assemblies
