The Newport 426 Linear Stage Positioner is a precision manual translation stage engineered for repeatable single-axis positioning in demanding optical, microscopy, and semiconductor applications. Featuring crossed-roller bearings on ground steel V-ways, the stage delivers high-resolution motion with minimal runout and substantial load capacity across a compact footprint. Its aluminum construction, non-influencing locking mechanism, and hardened carbide actuator interface eliminate backlash while maintaining angular accuracy, making it ideal for critical alignment tasks requiring micron-level control.

– Key Features
• Crossed-roller bearings on ground steel V-ways for high-resolution movement and low runout
• Non-influencing lock secures travel position without affecting stage alignment
• Hardened carbide insert with spring preload eliminates actuator backlash
• Side-drive configuration for compact integration
• Symmetrical design permits reconfiguration for left- or right-handed operation
• Interferometrically tested for performance consistency and reliability
– Typical Applications
• Optical system alignment and beam positioning
• Microscopy specimen and objective positioning
• Semiconductor wafer and component placement
• Precision mechanical scanning and measurement setups
– Compatibility & Integration
Stages stack readily for XY multi-axis applications. Three-axis (XYZ) configurations are achieved by combining the 426 with the Model 360-90 Slotted Angle Bracket. The stage accepts Newport manual actuators (AJS100-1 adjustment screw, SM-25 vernier micrometer, DMH-1 digital micrometer, DM-25L lockable micrometer) and motorized actuators (TRA25CC, TRA25PPD, TRB25CC, TRB25PP, LTA-HS).
