ZOLIX OMHS-LBE22/WJ/CMount Tri-Axis Precision Optical Mount Series

Overview

The ZOLIX OMHS-LBE22/WJ/CMount series represents a family of tri-axis precision optical mounts engineered for high-stability alignment in demanding laboratory and industrial optical setups. Unlike conventional two-dimensional kinematic mounts, each variant integrates orthogonal angular adjustment (pitch and yaw) with a dedicated axial (Z-direction) linear translation mechanism—enabling simultaneous beam steering and focus positioning without requiring secondary stages. This architecture is grounded in the OMHS (Opto-Mechanical Hybrid Structure) platform, a modular, rigid aluminum alloy chassis designed to minimize thermal drift and mechanical hysteresis. The mounts operate on a differential micrometer-driven principle, where sub-arcminute angular resolution and micron-level axial repeatability are achieved through hardened stainless steel screws and preloaded brass bushings. They are intended for use in applications requiring stable, repeatable optical path definition—particularly in laser beam conditioning, microscope objective integration, and machine vision system calibration.

Key Features

• Tri-axis adjustment capability: Independent pitch, yaw, and axial (Z) translation—eliminating need for stacked or auxiliary translation stages
• Three application-optimized interface variants: OMHS-LBE22 (M22×0.75 thread) for ZOLIX LBE-series beam expanders; OMHS-WJ (4/5″–1/36 UNC) for standard microscope objectives including Nikon CFI, Olympus UIS2, and Leica HCX series; OMHS-CMount (1″–1/32 UNC) for C-mount lenses, scientific CCD/CMOS cameras, and fiber collimators
• Angular range: ±3° per rotational axis with <15 arcsec minimum incremental resolution (based on 100 µm/rev micrometer scale and 10:1 reduction)
• Axial translation travel: 5 mm total range with lockable fine-adjustment knob and engraved scale (0.01 mm graduation)
• Structural integrity: CNC-machined 6061-T6 aluminum housing with black anodized finish (hardness ≥60 HV), ensuring dimensional stability under thermal gradients up to ±5 °C
• Mounting compatibility: Standard 1/4″–20 and M6 threaded holes on baseplate for secure attachment to optical tables, rails, or custom fixtures

Sample Compatibility & Compliance

These mounts accommodate optics conforming to widely adopted mechanical standards across academic, metrology, and OEM environments. The WJ variant supports objectives compliant with ISO 8039 (microscope objective mounting threads) and ANSI/ISO 10110-7 (surface form tolerances). The CMount version adheres to IEEE 1588-compliant imaging system integration protocols when used with time-synchronized camera modules. All variants meet RoHS 2011/65/EU directive requirements for hazardous substance restriction. While not certified to IEC 61326-1 (EMC) or ISO 14001 (environmental management), their passive mechanical design ensures immunity to electromagnetic interference and zero power consumption—making them suitable for ultra-low-noise interferometric and quantum optics experiments. Documentation includes full dimensional drawings (GD&T annotated per ASME Y14.5–2018) and material traceability reports for aerospace-grade aluminum batches.

Software & Data Management

As purely manual, non-motorized optomechanical components, the OMHS series requires no firmware, drivers, or software integration. However, they are fully compatible with industry-standard alignment workflows in MATLAB-based optical modeling (e.g., using PhasedArray System Toolbox for beam propagation analysis), Python-controlled motion platforms (via serial-commanded translation stages mounted alongside), and LabVIEW-based DAQ systems where positional metadata is logged via external encoders. For GLP/GMP-regulated environments, users may document mount configurations using ZOLIX’s optional calibration certificate package (traceable to NIST SRM 2036 via third-party metrology lab), which includes angular deviation maps and axial backlash measurements at three load points (0 N, 2 N, 5 N).

Applications

• Laser beam expansion and collimation alignment in Ti:sapphire and DPSS laser systems
• Objective lens positioning in confocal, multiphoton, and light-sheet microscopy platforms
• C-mount camera registration in spectral imaging, fluorescence lifetime (FLIM), and OCT systems
• Free-space optical interconnect alignment in photonic integrated circuit (PIC) testing benches
• Educational optics labs for teaching ray matrix formalism and ABCD propagation theory
• Calibration of wavefront sensors (Shack–Hartmann, lateral shearing interferometers) requiring sub-pixel beam centering

FAQ

Are these mounts compatible with non-ZOLIX optical components?
Yes—the LBE22, WJ, and CMount interfaces follow open mechanical standards; third-party beam expanders, objectives, and lenses with matching thread specifications will mount mechanically and functionally.
What is the maximum recommended load capacity per variant?
Static load limit is 1.2 kg for OMHS-LBE22 and OMHS-CMount, and 0.8 kg for OMHS-WJ (due to cantilever moment constraints of objective mounting geometry).
Do the mounts include locking mechanisms?
Each adjustment axis features dual-action locking: primary friction lock via knurled collar and secondary jam-lock via setscrew—ensuring positional retention during vibration or transport.
Is thermal expansion compensated in the design?
No active compensation is implemented; however, the symmetric OMHS chassis geometry and matched CTE (23.6 × 10⁻⁶/K) between aluminum body and stainless steel screws reduce relative misalignment to <0.5 arcsec/°C over operational range.
Can I order custom thread adapters or extended travel versions?
ZOLIX offers OEM customization—including metric/imperial thread conversions, vacuum-compatible versions (CF flange mounting), and extended Z-travel (up to 10 mm) upon formal engineering review and MOQ agreement.
