The Newport 433 Series is a precision linear translation stage engineered for high-stability optical component positioning. Single-row ball bearing construction with hardened, polished stainless steel rods delivers angular deviation below 200 µrad. A hardened carbide insert contact point ensures smooth motion while preload springs eliminate backlash. The stage accepts both manual and motorized actuators (sold separately) and supports right-hand or left-hand configuration for flexible multi-axis stacking.
