Newport 423 Vertical Linear Stage
The 423 linear translation stage with its large 3 in. square platform features exceptional performance, usability, and value with precision ball bearing construction – hardened balls rolling between opposing pairs of hardened and polished stainless steel rods providing better than 200 microradian angular deviation. For stability, repeatability, and exceptionally smooth motion, actuators bear upon a hardened carbide insert. Springs provide preload against the actuator tip to eliminate backlash. Although the stage is capable of traveling a full 1 in. (25.4 mm) with the SM-25 micrometer drive, the actuator mounting blocks can be relocated to accommodate 0.5 in. (12.7 mm) drives like the SM-13. This stage can also be reconfigured into a left-handed version with the micrometer on the opposite side. A non-influencing lock (also reversible for left-handed configuration) provides positive stable positioning and guards against inadvertent adjustments. Actuators for this stage are sold separately.
