RTLA Series motorized rotation stages provide precision angular positioning accuracy combined with

high load capacity. All RTLA stages are constructed of anodized aluminum, 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 two phase stepper motors

with programmable micro-stepping resolutions to provide sub arc-sec angular positioning.
