Optical Mounts Series OMHS, OMMB, OMLH

Overview

The Optical Mounts Series (OMHS, OMMB, OMLH) is a precision-engineered family of manual optical positioning components designed for stable, repeatable alignment and fixation of optical elements—including mirrors, lenses, filters, prisms, and laser crystals—in research-grade optical benches, educational laboratories, and industrial optomechanical systems. These mounts operate on fundamental principles of six-degree-of-freedom (6-DOF) mechanical constraint: translation along X/Y/Z axes and rotation about pitch, yaw, and roll. Each variant is purpose-built to deliver controlled adjustment within defined tolerance envelopes while maintaining long-term dimensional stability under thermal cycling and mechanical vibration typical in Class 1000 cleanrooms or university teaching labs. Unlike motorized or piezoelectric alternatives, this series prioritizes mechanical simplicity, tactile feedback, and deterministic repeatability—making it especially suitable for setups requiring infrequent but high-fidelity reconfiguration, such as interferometer alignment, cavity stabilization, or fiber-coupling optimization.

Key Features

• Modular Design Architecture: Structured across six functional subfamilies—OM (Optic Mounts), AP (Application-Specific), AC (Accessories), BP (Base Plates), PH (Posts & Holders), and RA (Rails & Carriers)—enabling scalable system integration from single-element mounting to multi-stage kinematic platforms.
• Material-Specific Construction: Primary structural components fabricated from anodized 6061-T6 aluminum (standard), low-carbon steel (high-load variants), or oxygen-free copper (EMI-sensitive or cryogenic applications), each selected for optimal stiffness-to-mass ratio, thermal expansion coefficient matching, and surface finish consistency.
• Manual Drive Mechanisms: Equipped with either ultra-fine-pitch (0.25 mm) stainless-steel adjustment screws for high-resolution angular/linear tuning or calibrated micrometer heads (dial resolution ±1 µm, repeatability ±3 µm) for quantitative displacement control—fully compatible with ISO 9001-certified calibration workflows.
• Kinematic Compatibility: All OM-series mounts feature standardized M4, M6, or 1/4″-20 threaded holes conforming to Thorlabs, Newport, and Standa mounting interface conventions; base plates include metric and imperial grid patterns (25 mm and 1″ spacing) for cross-platform interoperability.
• Environmental Robustness: Surface treatments include hard-anodization (≥50 HV hardness), passivation (for steel variants), and optional black oxide coating—ensuring resistance to oxidation, fingerprint corrosion, and particulate adhesion per ISO 14644-1 Class 8 cleanroom requirements.

Sample Compatibility & Compliance

This mount series accommodates optical components ranging from Ø3 mm micro-optics to Ø100 mm collimation lenses, with clamping force adjustable from 0.5 N to 12 N depending on model configuration. Mounting interfaces support plano-convex, meniscus, cylindrical, and custom-aspheric optics with edge thicknesses from 1.5 mm to 25 mm. All models comply with mechanical safety standards outlined in ISO 12100 (risk assessment) and EN 61000-6-2 (electromagnetic immunity). While not certified for medical device use, the design adheres to GLP-relevant documentation traceability protocols—including batch-specific material certifications (mill test reports), surface roughness verification (Ra ≤ 0.8 µm), and assembly torque logs archived per customer request.

Software & Data Management

As purely mechanical positioning hardware, these optical mounts require no firmware, drivers, or proprietary software. However, they are fully documented in industry-standard CAD formats (STEP AP214, IGES) and integrated into common optical design environments including Zemax OpticStudio (via native .ZMX mount libraries), CODE V (as .DAT kinematic models), and FRED (with ray-trace-ready GDML definitions). For quality assurance, each shipment includes a digital compliance dossier containing dimensional inspection reports (CMM-measured critical features), surface finish certificates, and RoHS/REACH declaration of conformity—structured for seamless ingestion into LIMS or QMS platforms compliant with ISO/IEC 17025.

Applications

• Laser cavity alignment in DPSS and fiber laser development labs
• Fiber-to-free-space coupling optimization in telecom R&D (ITU-T G.652/G.657 compatibility)
• Interferometric setup stabilization for gravitational wave prototype experiments
• UV-VIS-NIR spectrometer optical path assembly (per ASTM E275 and ISO 10110-7)
• Undergraduate optics pedagogy: Michelson, Mach-Zehnder, and Fabry-Pérot demonstrations
• Industrial machine vision illumination train calibration (ISO 16508-2 compliant)

FAQ

Are these mounts compatible with vacuum environments?
Yes—aluminum variants (OMHS-AL, OMLH-AL) are rated for operation at pressures down to 1×10⁻⁵ mbar when assembled with vacuum-compatible lubricants (e.g., Braycote 601 EF); copper versions support cryogenic vacuum (<77 K) with prior bake-out.
Do you provide metrology data for individual units?
Upon request, CMM validation reports (including positional accuracy ±2.5 µm over 50 mm travel, angular deviation <5 arcsec per full turn) can be supplied with serial-number traceability.
Can I integrate these mounts with motorized stages?
All base plates and posts feature tapped holes aligned to standard motion stage footprints (e.g., Newport UVP series, PI M-406); custom adapter plates are available under NDA.
What is the maximum load capacity for OMHS-series mirror mounts?
Standard OMHS-25 supports up to 1.2 kg at center-of-gravity offset ≤5 mm; heavy-duty OMHS-50 variants sustain 4.8 kg with dynamic stability verified per MIL-STD-810G Method 514.6.
Is RoHS certification available for export to EU markets?
Yes—full substance declarations and third-party testing reports (SGS, TÜV Rheinland) are included in every commercial invoice package.
