ZOLIX OMLH120 / OMLH120-160 Square Optical Mirror Mount

Overview

The ZOLIX OMLH120 and OMLH120-160 are precision-engineered square optical mirror mounts designed for stable, repeatable alignment and secure clamping of rectangular optical elements in laboratory and industrial optical setups. These mounts operate on a kinematic three-point contact principle—two fixed contact points and one adjustable locking point—to minimize stress-induced birefringence and deformation in mounted optics while ensuring high angular stability. Constructed from high-rigidity anodized aluminum alloy (6061-T6), the mount body exhibits low thermal expansion, dimensional stability under ambient fluctuations, and resistance to oxidation in standard cleanroom and benchtop environments. The OMLH120 accommodates rectangular optics up to 120 mm × 120 mm; the extended variant OMLH120-160 supports optics up to 160 mm × 120 mm, with identical mounting geometry and adjustment interface. Both models feature M6 threaded holes on the base plate for direct integration into standard optical tables (e.g., Thorlabs, Newport) or custom mechanical stages.

Key Features

• Modular square-frame design optimized for uniform load distribution across rectangular substrates, reducing edge chipping and surface distortion during clamping.
• Adjustable stainless-steel retaining clips with fine-pitch knurled thumbscrews (M4 × 0.7) enabling precise pressure control—critical for low-stress mounting of coated, thin, or fragile optics (e.g., AR-coated fused silica, ITO glass, or polymer-based filters).
• Integrated 360° rotational base with dual-axis tilt adjustment (±4° pitch/yaw range) via two orthogonal micrometer-driven actuators (10 µm resolution), facilitating coarse and fine alignment without repositioning the entire mount.
• Interchangeable mounting plates: Standard configuration includes a 12-mm-thick aluminum base with four M6 × 12 mm counterbored holes; optional stainless-steel or black-anodized variants available for vacuum compatibility (UHV-rated up to 10⁻⁶ mbar) or ESD-sensitive applications.
• Metric-threaded accessory interface: Four M4 threaded ports on the vertical flange allow attachment of kinematic tip/tilt adapters, translation stages, or fiber-optic collimator brackets without additional adapters.

Sample Compatibility & Compliance

The OMLH120/OMLH120-160 series is compatible with plano and wedged rectangular optics ranging from 25 mm × 25 mm to 160 mm × 120 mm in dimension and 2 mm to 25 mm in thickness—including laser mirrors, beam splitters, polarizers, waveplates, and interference filters. Mounting force is mechanically limited to ≤80 N per clip to prevent substrate fracture or coating delamination. All components comply with ISO 9001:2015 manufacturing controls and conform to RoHS Directive 2011/65/EU for hazardous substance restrictions. Surface finish meets ISO 10110-7 specifications (Rₐ ≤ 0.8 µm on critical contact surfaces). No CE marking is applied, as the product is classified as a passive mechanical optical component—not an active device requiring EMC or LVD certification.

Software & Data Management

As a purely mechanical, non-electronic optical mount, the OMLH120/OMLH120-160 requires no firmware, drivers, or software integration. However, its standardized metric threading and geometric repeatability support seamless incorporation into automated optical alignment workflows when paired with motorized translation or rotation stages (e.g., ZOLIX KSA-series or third-party controllers). CAD models (STEP, IGES, and SolidWorks formats) are provided upon request for mechanical integration validation. Mounting position data—including orientation angles, center-of-mass offsets, and thermal drift coefficients—can be logged in LabVIEW, MATLAB, or Python-based optical system modeling frameworks (e.g., PyOptica, OptoPy) for full-system error budgeting and tolerance analysis.

Applications

• Laser cavity construction and alignment for DPSS, Ti:sapphire, and fiber lasers—particularly where rectangular gain media or Brewster-cut crystals require rigid, low-stress fixation.
• Interferometric systems (e.g., Mach–Zehnder, Michelson) demanding long-term angular stability (<0.5 arcsec drift over 24 h at 23 ± 1 °C).
• Optical coherence tomography (OCT) beam delivery arms, where rectangular scanning mirrors must maintain flatness under dynamic acceleration.
• UV-VIS-NIR spectrometer slit assemblies and monochromator output couplers, where rectangular filter stacks require orthogonal mounting without lateral shift.
• Educational optics labs: Used in undergraduate photonics courses to demonstrate polarization manipulation, beam steering, and wavefront correction using discrete rectangular elements.

FAQ

What is the maximum recommended optic thickness for the OMLH120-160 model?

Optics up to 25 mm thick can be securely clamped; for substrates >15 mm, use spacers to ensure even clip engagement and avoid cantilever bending.
Can these mounts be used in vacuum environments?

Yes—the base plate and clips are UHV-compatible when ordered with stainless-steel construction and vacuum-baked assembly; standard anodized aluminum versions are rated for low-to-medium vacuum only (≤10⁻³ mbar).
Is there backlash in the tilt adjustment mechanism?

Micrometer actuators employ anti-backlash nuts with preloaded bronze bushings, yielding <5 µm hysteresis over full travel.
Do you supply custom engraving or OEM branding?

Yes—laser etching of serial numbers, part IDs, or customer logos is available on the base plate flank per ISO/IEC 15415 verification standards.
Are replacement clips or screws available as spare parts?

All fasteners and retaining clips are cataloged under ZOLIX Part Numbers OMLH-CLIP-SS and OMLH-SCREW-M4-0.7, stocked globally through authorized distributors.
