Overview
The ZOLIX OMUS Series Ultra-Stable Optical Mounts are precision-engineered kinematic adjustment platforms designed for demanding optical alignment tasks in research-grade laser systems, interferometry setups, quantum optics laboratories, and high-stability spectroscopic instrumentation. These mounts operate on the principle of three-point kinematic constraint—leveraging precisely ground stainless-steel contact surfaces, low-hysteresis elastic elements, and micro-translation mechanisms—to minimize thermal drift, mechanical creep, and vibration-induced misalignment over extended operational periods. Unlike standard aluminum or brass optical mounts, the OMUS series prioritizes long-term positional fidelity under static load and dynamic thermal cycling, making it suitable for applications requiring sub-microradian angular stability and sub-micron translational repeatability over hours or days.
Key Features
- 304 Stainless Steel Construction: Entire structural body—including base plate, adjustment plates, springs, and threaded components—is fabricated from passivated 304 stainless steel, providing superior dimensional stability, corrosion resistance, and compatibility with high-vacuum environments (≤10⁻⁶ mbar) when paired with vacuum-rated lubricants.
- Four-Spring Symmetric Actuation: All models except the 12.7 mm variant utilize four radially symmetric tension springs to balance axial forces across the adjustment axis, reducing torque-induced tilt and ensuring uniform load distribution during fine positioning.
- Ultra-Fine-Pitch Adjustment Mechanism: Equipped with 0.2 mm pitch precision-ground brass-on-stainless-steel threaded actuators (excluding 12.7 mm model), delivering theoretical angular resolution better than 2 arcseconds per full turn under typical loading conditions.
- Dual-Lock Design: Each adjustment screw incorporates an integrated locking collar; additionally, both front and rear mounting plates feature dedicated M4 locking-thread holes to secure the entire mount against external vibration or accidental bumping.
- Hybrid Adjustment Interface: Rear-mounted hex socket allows direct actuation via 2 mm Allen key for high-torque coarse positioning, while a standard 12 mm hex interface supports optional ZOLIX precision handwheel (sold separately) for enhanced ergonomics and finer control.
- Non-Deforming Mirror Retention: Standard configurations include spring-loaded flexure clips actuated by set screws—designed to apply distributed radial preload rather than point-contact clamping, mitigating stress birefringence and surface distortion in coated optics up to 25 mm diameter.
Sample Compatibility & Compliance
The OMUS series accommodates plano and spherical mirrors, windows, and polarizers with diameters ranging from 12.7 mm to 50.8 mm (custom sizes available upon request). Mounting interfaces conform to ISO 80000-4 mechanical units and follow ANSI/BHMA A156.19 dimensional conventions for optical hardware. All materials comply with RoHS Directive 2011/65/EU and meet outgassing requirements per ASTM E595 for space-qualified optical subsystems. Vacuum compatibility is validated per NASA MSFC-SPEC-177A when used with Fomblin Y-25 lubricant and baked at 120 °C for 24 hours.
Software & Data Management
While the OMUS series is a purely manual, non-motorized optical mount, its mechanical design is fully compatible with third-party motion control ecosystems. Standard M4 and M6 tapped holes on the rear plate allow rigid integration with motorized translation stages (e.g., Thorlabs K10CR1, Newport UVPD100) and position-sensing platforms. CAD models (STEP, IGES) and GD&T-controlled drawings are provided for seamless integration into LabVIEW-, MATLAB-, or Python-driven alignment workflows. Traceable calibration reports—including angular repeatability test data under 1 g acceleration—are available upon request for GLP-compliant laboratory documentation.
Applications
- Laser cavity alignment in ultrafast Ti:sapphire and fiber amplifier systems
- Stabilization of reference arms in Michelson and Mach–Zehnder interferometers
- Mounting of etalons and Brewster-angle windows in high-finesse resonators
- Positioning of dichroic filters and waveplates in multi-wavelength quantum entanglement experiments
- Long-duration environmental testing of optical path stability under thermal gradient exposure (−20 °C to +60 °C)
- Integration into vacuum-compatible ultra-high-resolution Raman spectrometers
FAQ
Can the OMUS mount be used in ultra-high vacuum (UHV) environments?
Yes—when assembled with vacuum-compatible lubricants (e.g., Fomblin, Braycote 601) and baked per standard UHV protocols, the 304 stainless steel construction ensures minimal outgassing and no polymer degradation.
Is the flexure clip removable without compromising functionality?
Yes—the clip is mechanically independent; removal exposes standard set-screw contact points, enabling conventional rigid clamping while retaining full adjustability.
What is the maximum recommended optic weight for OMUS-25.4?
For optimal angular stability and repeatability, the OMUS-25.4 model supports optics up to 120 g with center-of-mass within 3 mm of the optical axis.
Are metric and imperial mounting accessories included?
All units ship with M4 cap screws and washers; M6 adapters and ¼”-20 threaded inserts are available as optional accessories.
Does ZOLIX provide ISO/IEC 17025-accredited calibration for OMUS mounts?
Calibration certificates traceable to NIM (National Institute of Metrology, China) are available; full ISO/IEC 17025 accreditation applies to ZOLIX’s metrology lab for custom verification services.
