Newport 433 Series – Optical Stage

The Newport 433 Series Optical Stage is a precision single-axis linear translation stage engineered for accurate positioning of optical components in research and development environments. Built on aluminum construction with single-row ball bearing guidance, it delivers backlash-free motion across 46 mm (1.81 in.) of travel on a compact 3.0 × 4.0 in. platform. Spring preload eliminates play against the actuator tip, while a non-influencing lock mechanism ensures stable positioning without drift. Angular deviation remains below 200 µrad, meeting stringent alignment requirements.

– Key Features

• Backlash-free motion via precision ball bearing construction and spring preload
• Relocatable actuator mounting blocks accommodate different drive sizes (SM-50 for 46 mm travel, SM-25 for 25.4 mm travel)
• Configurable for left or right-handed operation with switchable lock and micrometer positions
• Stackable design enables multi-axis configurations
• Compact, low-profile footprint (1.0 in. height) suitable for space-constrained setups

– Compatibility & Integration

Supports both manual and motorized actuation. Compatible with SM-50 micrometer actuators, AJS100-2 adjustment screws, and LTA-HS motorized actuators (sold separately). Actuator mounting flexibility allows reconfiguration without redesign.
