Newport 422-1S Miniature Linear Stage PLUS

The Newport 422-1S is a miniature single-axis linear stage delivering 1 µm resolution over a 25 mm travel range. Built on precision ground rails with single-row ball bearings and spring-loaded 80-pitch adjustment screws, it provides smooth, accurate linear motion in a compact aluminum housing. The stage handles 71 N centered normal load and 44 N vertical axial load while maintaining angular deviation below 200 µrad. Its stackable design enables multi-axis configurations—X-Y motion through direct stacking, or X-Y-Z using the optional Model 411B reversible bracket. The drive mechanism can be removed for external actuation when required. Precision mounting interfaces accept 8-32 and 1/4-20 threads and integrate with SP Series post-mounting systems, making it ideal for opto-mechanical instrumentation and laboratory positioning tasks where compact form factor and micron-level accuracy are essential.
