The Newport 423 is a precision linear translation stage engineered for accurate, repeatable positioning across single-axis applications. This aluminum-bodied stage delivers 25 mm (1 inch) of travel with exceptional motion smoothness through hardened carbide insert actuator contact and preload springs that eliminate backlash. The single-row ball bearing design ensures stability and angular deviation below 200 µrad, while a non-influencing lock mechanism maintains position integrity. The low-profile 3.0 × 3.0 in. platform accommodates both manual and motorized actuators via reconfigurable side-drive mounting, and supports left or right-handed operation for flexible integration into multi-axis systems.

– Key Features
• Hardened carbide insert actuator contact surface for smooth, consistent motion
• Preload springs eliminate backlash and ensure positioning repeatability
• Non-influencing lock provides stable hold without affecting stage geometry
• Configurable for left or right-handed operation; lock and micrometer positions switchable
• Side-drive actuator mounting allows relocation for different actuator sizes
• Low-profile design optimizes vertical envelope in compact optical and mechanical systems
– Typical Applications
Precision positioning in optical alignment, sample manipulation, beam steering, and laboratory instrumentation where single-axis linear motion with high repeatability and minimal angular deviation is required.
– Compatibility & Integration
The 423 accepts both manual actuators (e.g., SM-25 for 25 mm travel, SM-13 for 13 mm travel) and motorized drive options. Actuators are sold separately for certain configurations. Multiple stages stack for multi-axis XY, XYZ, and rotary system construction. Mounting provisions accept 1/4-20 and M6 fasteners depending on model variant.
