Overview
The ZOLIX OMHS38.1/50-S is a precision-engineered three-axis optical mirror mount designed for demanding alignment tasks in research-grade optical laboratories, laser systems integration, and interferometric setups. Built upon a monolithic stainless-steel base with hardened adjustment screws and kinematic contact geometry, this mount delivers exceptional thermal stability, mechanical rigidity, and long-term positional retention—critical attributes for applications requiring sub-arcminute angular repeatability and micron-level translational control. Its dual configuration supports both 38.1 mm (1.5″) and 50 mm (or 50.8 mm / 2″) optics, accommodating standard mirror substrates used in ultrafast laser cavities, spectroscopic beam paths, and adaptive optics test benches. The mount operates on a proven three-degree-of-freedom principle: two orthogonal tip/tilt axes (pitch and yaw) and one linear translation axis (Tx), enabling precise collimation, beam steering, and focal plane positioning without inducing parasitic lateral shifts or rotational coupling.
Key Features
- Monolithic stainless-steel construction with black oxide finish for enhanced corrosion resistance and dimensional stability across ambient temperature fluctuations (±0.5 °C).
- Kinematic mounting interface with three-point contact design minimizes stress-induced birefringence in coated optics and ensures consistent clamping force distribution.
- High-resolution differential micrometer screws (10 µm per division, 0.5 mm pitch) provide smooth, backlash-free angular adjustment over ±3° range in both pitch and yaw axes.
- Linear Tx stage features precision-ground leadscrew and anti-rotation guide pin, delivering 6 mm of repeatable, non-rotating translation with ≤1 µm hysteresis over full travel.
- Optimized clear apertures—35 mm for 38.1 mm optics and 47 mm for 50 mm optics—maximize usable beam area while maintaining structural integrity and minimizing diffraction edge effects.
- Integrated M4 and M6 threaded mounting holes on base plate enable rigid attachment to optical tables, breadboards, or custom kinematic platforms per ISO 8015 tolerancing standards.
Sample Compatibility & Compliance
The OMHS38.1/50-S accommodates plano, concave, and dielectric-coated mirrors with thicknesses ranging from 3 mm to 12 mm, including common fused silica, BK7, and UV-grade CaF₂ substrates. It complies with general laboratory safety requirements for optical hardware (IEC 61000-6-3 EMC emission limits) and meets mechanical interface specifications outlined in ANSI/OEOSC OP1.002–2021 for optical mounts. While not certified to ISO 9001 as a standalone component, it is manufactured under ZOLIX’s ISO 9001:2015-certified quality management system, ensuring traceable material sourcing, calibrated assembly procedures, and 100% functional testing prior to shipment. No hazardous substances are used in its fabrication; RoHS 3 (2015/863/EU) compliance is verified via third-party material declaration.
Software & Data Management
This passive mechanical mount does not incorporate electronic actuation or embedded firmware; therefore, it requires no driver installation, firmware updates, or software interface. All adjustments are performed manually using standard 2 mm hex keys. For integration into automated alignment workflows, the OMHS38.1/50-S is fully compatible with industry-standard motorized stages (e.g., Thorlabs K10CR1, Newport U-523) when mounted via optional adapter plates. Documentation includes bilingual (English/Chinese) PDF manuals with dimensional drawings (GD&T annotated per ASME Y14.5–2018), torque specifications for clamping screws (0.35–0.45 N·m), and recommended maintenance intervals (biannual inspection of screw preload and bearing surface wear).
Applications
- Laser cavity alignment in Ti:sapphire, fiber, and diode-pumped solid-state laser systems where pointing stability < 2 µrad over 8 hours is required.
- Beam combining and spatial filtering in Michelson and Mach–Zehnder interferometers operating at 266 nm to 10.6 µm wavelengths.
- Optical path length tuning in Fourier-transform infrared (FTIR) spectrometers and cavity ring-down spectroscopy (CRDS) platforms.
- Alignment of off-axis parabolic mirrors in ultrafast pulse compression and beam delivery systems.
- Education and training labs where robustness, tactile feedback, and intuitive kinematic behavior support pedagogical understanding of ray optics and wavefront manipulation.
FAQ
Can the OMHS38.1/50-S be used in vacuum environments?
Yes—it is compatible with high-vacuum conditions up to 1×10⁻⁶ mbar when assembled with vacuum-rated lubricants (e.g., Braycote 601 EF) and without elastomeric gaskets.
Is there an option for motorized actuation?
No built-in motorization is available; however, third-party stepper or piezo actuators can be retrofitted using the standardized M4/M6 mounting pattern and documented mechanical envelope.
What is the maximum recommended optic weight?
For optimal angular stability and minimal drift, the mount is rated for optics up to 350 g at room temperature; heavier loads require verification of center-of-mass alignment relative to the kinematic pivot point.
Does ZOLIX provide calibration certificates for angular repeatability?
Calibration reports documenting angular repeatability (≤±2 arcsec over 100 cycles) and Tx linearity (±0.8 µm over full stroke) are available upon request at additional cost.
Are replacement parts such as adjustment screws or clamping rings available separately?
Yes—all mechanical subcomponents—including differential screws, spring washers, and nylon-tipped clamping rings—are stocked and supplied with individual part numbers for traceable replacement.
