RTLA Series motorized rotation stages provide precision angular positioning accuracy combined with
high load capacity. All RTLA stages are constructed from steel or anodized aluminum (model dependent), with rotation accuracy ensured by
the precision bearings and ground worm gear drive system. The single monolithic design offers improved stiffness
without compromising dynamic performance. RTLA stages are driven by the stepper or servo motors
with resolutions to provide sub arc-sec angular positioning.
