SMGON Series Precision Direct-Drive Manual Tip/Tilt Stage for Vacuum Environments

Overview

The SMGON Series Precision Direct-Drive Manual Tip/Tilt Stage for Vacuum Environments is an engineered optical positioning solution designed for high-stability angular adjustment under ultra-high vacuum (UHV) and cleanroom-compatible conditions. Unlike conventional worm-gear or geared tilt stages, the SMGON series implements a direct-coupled micrometer drive mechanism acting on a kinematically constrained arc-shaped V-groove ball bearing rail system. This architecture eliminates backlash and hysteresis, enabling sub-arcminute repeatability and smooth, friction-minimized angular motion in both pitch and yaw axes. The stage is constructed entirely from non-magnetic, low-outgassing AISI 304 stainless steel—certified for bake-out up to 150 °C—and features surface passivation per ASTM A967 to ensure long-term vacuum integrity. Its mechanical design complies with ISO 10110-7 (optical component mounting interfaces) and adheres to UHV material selection guidelines outlined in ESA/SCC Basic Specification No. 11000.

Key Features

• Direct micrometer-driven tip/tilt actuation with 0.5 µm resolution per graduation and ≤2 arcsec minimum incremental motion
• Arc-shaped V-groove precision ball bearing rail system providing linearized angular displacement with <0.02% nonlinearity over full ±3° range
• Vacuum-rated construction: All fasteners, seals, and lubricants meet ISO 14644-1 Class 4 particulate limits and outgassing rates per ASTM E595 TC <1.0%, CVCM <0.1%
• Standardized top plate featuring 25 mm grid-pattern M4 threaded holes compatible with Thorlabs, Newport, and Standa mounting accessories
• Integrated base-mounting pattern with four M6 through-holes aligned to ISO 2080 standard spacing for rigid multi-axis stack integration
• No internal elastomers or organic adhesives—fully compatible with electron-beam lithography, synchrotron beamline, and cryogenic optical alignment applications

Sample Compatibility & Compliance

The SMGON stage supports optical components ranging from Ø12.7 mm lens mounts to 100 × 100 mm mirror substrates, provided mass does not exceed 2.5 kg and center-of-gravity remains within ±8 mm of the stage’s central axis. It has been validated for use with fused silica, CaF₂, and BK7 optics under thermal cycling from −40 °C to +80 °C. Compliance documentation includes RoHS 2011/65/EU, REACH SVHC declaration, and vacuum compatibility test reports per ISO 27862:2017 Annex B. The stage meets mechanical interface requirements for integration into ISO-KF40 and CF63 vacuum flange systems when used with optional adapter plates.

Software & Data Management

As a manually operated stage, the SMGON series requires no firmware, drivers, or software dependencies. However, its standardized mechanical interface enables seamless integration with third-party motion control ecosystems—including Zaber’s T-CA series controllers, PI’s C-867 controllers, and LabVIEW-based DAQ systems—via optional motorized conversion kits (sold separately). All calibration data, including angular deviation maps and thermal drift coefficients (measured at 23 ±0.5 °C per ISO 230-2), are provided in NIST-traceable PDF and CSV formats. Audit trails for manufacturing lot traceability, material certifications, and vacuum test logs are available upon request for GLP/GMP-regulated laboratories.

Applications

• Precision alignment of laser cavity mirrors and output couplers in UHV Ti:sapphire and fiber laser systems
• Angle-resolved photoemission spectroscopy (ARPES) sample goniometers requiring long-term thermal stability
• Interferometric optical path length tuning in Michelson and Mach–Zehnder configurations
• Beam steering and collimation correction in EUV lithography mask inspection tools
• Multi-axis kinematic mounts for adaptive optics wavefront correction assemblies
• Calibration reference platforms for autocollimators and electronic levels per ISO 230-5

FAQ

Is the SMGON stage compatible with magnetic environments?
Yes—the entire structure uses non-magnetic AISI 304 stainless steel, with measured relative permeability μᵣ < 1.02 across DC–1 MHz, making it suitable for MRI-adjacent optical setups and particle accelerator beamlines.
What is the maximum allowable load moment about the tilt axis?
The stage maintains angular repeatability within ±3 arcsec up to a static moment load of 0.8 N·m; dynamic loads exceeding 0.3 N·m require external damping or active stabilization.
Can this stage be baked in situ inside a vacuum chamber?
Yes—validated for continuous bake-out at 150 °C for 24 hours without dimensional shift >±0.5 µm or angular drift >±1 arcsec, per ASTM E1543 thermal stability protocol.
Are custom aperture or port configurations available?
ZOLIX offers OEM mechanical redesign services—including side-port cutouts, integrated feedthroughs, and flange-mounted encoder brackets—under NDA with lead times starting at 8 weeks.
