The Newport 431 Linear Stage paired with the MICRO controller delivers precise linear motion for laboratory, research, and industrial positioning tasks. Built on crossed-roller bearings running ground steel V-ways, the stage achieves smooth, stable movement under high load. Preloaded springs eliminate actuator backlash, ensuring repeatability across demanding applications. The 431 platform measures 4″ × 3″ and accepts motorized actuators (sold separately) for automated control. Angular deviation is less than 150 µrad. The stage reconfigures for left- or right-hand mounting with a non-influencing lock for positive positioning. Extended platforms feature center apertures and generous hole patterns; mounting bases are removable for lower-profile integration.
