ZOLIX OMRS38.1/50-BS Two-Axis High-Stability Mirror Mount

Overview

The ZOLIX OMRS38.1/50-BS is a precision-engineered two-axis optical mirror mount designed for demanding alignment tasks in research-grade optical laboratories and industrial laser systems. It operates on a dual-stage kinematic adjustment principle—employing orthogonal micrometer-driven tip-tilt mechanisms—to enable independent, decoupled control of pitch and yaw axes. This architecture minimizes crosstalk between angular degrees of freedom, ensuring high-fidelity beam steering and long-term pointing stability under thermal drift or mechanical vibration. The mount is optimized for use with standard Ø38.1 mm (1.5″) and Ø50 mm (or Ø50.8 mm / 2″) optics, accommodating both common metric and imperial-dimensioned mirrors without adapter plates. Its mechanical design prioritizes rigidity and hysteresis reduction, making it suitable for applications requiring sub-milliradian repeatability in static or quasi-static alignment workflows.

Key Features

• Two independently adjustable axes (pitch and yaw) with ±3° total angular range per axis, enabling precise collimation and beam redirection.
• Dual clamp diameter compatibility: supports optics with outer diameters of either 38.1 mm or 50 mm (including 50.8 mm), facilitating integration into diverse optical rail and cage systems.
• Clear aperture of 35 mm (for 38.1 mm version) and 47 mm (for 50 mm version) ensures minimal vignetting for typical laser beams and imaging paths.
• Direct-drive stainless steel micrometer actuators with knurled knobs provide tactile feedback and resistance to slippage during fine-tuning.
• Black anodized aluminum construction offers corrosion resistance, low thermal expansion, and compatibility with vacuum-compatible optional upgrades (e.g., non-outgassing hardware).
• Standard M4 and M6 threaded mounting holes on baseplate enable secure attachment to optical tables, breadboards, or custom fixtures using industry-standard fasteners.

Sample Compatibility & Compliance

The OMRS38.1/50-BS is compatible with plano, concave, and convex mirrors up to 12 mm thickness, provided their surface flatness meets λ/10 or better at 633 nm. It accommodates dielectric, metallic, and protected silver-coated substrates. While not certified to ISO 9001 or CE as a standalone component, the mount conforms to general mechanical safety and dimensional tolerancing practices aligned with ISO 2768-mK (medium tolerance class). It is routinely deployed in setups compliant with ISO/IEC 17025-accredited calibration laboratories when integrated into validated optical alignment procedures. No hazardous substances are used in its manufacturing per RoHS Directive 2011/65/EU Annex II.

Software & Data Management

This is a purely manual, analog optical mount with no embedded electronics, sensors, or digital interfaces. Therefore, it does not require firmware, drivers, or proprietary software. Alignment data—including angular settings, positional records, and calibration logs—is maintained externally via laboratory notebooks, LIMS entries, or electronic lab notebooks (ELNs) such as LabArchives or Benchling. For traceable metrology workflows, users may document micrometer dial readings alongside interferometric or quadrant photodiode-based beam position measurements. The mount’s mechanical simplicity supports full auditability under GLP and GMP-aligned quality systems where manual instrument logs are part of defined SOPs.

Applications

• Laser cavity alignment in DPSS, Ti:sapphire, and fiber laser systems.
• Interferometer setup (Michelson, Mach–Zehnder) requiring stable, repeatable mirror orientation.
• Optical coherence tomography (OCT) reference arm stabilization.
• Beam combining and steering in multi-wavelength spectroscopy platforms.
• Alignment of objective lenses and scanning galvanometers in confocal microscopy assemblies.
• Educational optics labs for teaching principles of ray tracing, wavefront error, and mechanical degrees of freedom in optical design.

FAQ

Is the OMRS38.1/50-BS compatible with motorized actuation?
No—this model is strictly manually operated. Motorized versions (e.g., with stepper or piezo actuators) are available under separate ZOLIX product codes and require external motion controllers.
Can it be used in vacuum environments?
The standard version is not vacuum-rated; however, ZOLIX offers modified variants with vacuum-compatible lubricants and vented screws upon request for UHV applications down to 10⁻⁷ mbar.
What is the angular resolution of the micrometer adjustments?
Resolution depends on user technique and micrometer scale graduation; typical interpretation is ~10 µrad per division, though actual reproducibility must be verified experimentally per ISO 10110-5.
Does it include locking mechanisms?
Yes—each axis features a dedicated lock screw to secure angular position after coarse/fine adjustment, minimizing drift during system operation.
Are replacement parts (e.g., micrometer knobs, clamping rings) available separately?
Yes—ZOLIX maintains spare parts inventory for all OMRS-series mounts, including OEM-specified springs, retaining rings, and calibrated micrometer assemblies.
