The large clear aperture with a diameter of 120 mm is a great advantage of the PRS-200 rotation stage. For maximum positional stability the body is fabricated from a special, high-rigidity, tempered aluminum alloy . Two calibrated preloaded zero backlash precision roller bearings guarantee excellent flatness and smooth motion. A hardened and precision and calibrated worm gear guarantee a quiet and smooth motion. As an option, the stages can be delivered with an integrated optical angular scale. PRS-200 rotation stages are equipped with two reference switches which can be easily adjusted by the customer. Drive variations including closed-loop DC servo or 2-phase stepper motors are available.
