The Newport 443 is a precision single-axis linear stage engineered for accurate positioning in research and industrial applications. Built on single-row ball bearing guidance with hardened, polished stainless steel rods, it delivers smooth motion with minimal angular deviation. The stage accepts two actuators (sold separately) configured tip-to-tip with spring preload to eliminate backlash, and supports manual adjustment screws, micrometers, or motorized actuators. A reversible non-influencing lock provides positive positioning while allowing reconfiguration for left or right-handed operation.
