ZOLIX OMRS38.1/50/50.8-CS Two-Axis High-Stability Mirror Mount

Overview

The ZOLIX OMRS38.1/50/50.8-CS is a precision-engineered two-axis kinematic mirror mount designed for demanding optical alignment tasks in research laboratories, metrology setups, and industrial laser systems. Built upon a rigid stainless-steel monolithic base with low-thermal-expansion geometry, this mount employs differential micrometer-driven kinematic adjustment mechanisms to deliver sub-arcminute repeatability and long-term angular stability under mechanical and thermal stress. Its dual-axis architecture enables independent, orthogonal control of pitch and yaw—critical for collimation, beam steering, cavity alignment, and interferometric path-length tuning. Unlike single-axis or flexure-based alternatives, the OMRS series utilizes hardened steel ball-and-cone contact points paired with backlash-free fine-thread actuators (100 µm/rev resolution), ensuring minimal hysteresis and high positional fidelity over repeated adjustments. The mount complies with standard optical breadboard mounting patterns (M6 threaded holes on 25 mm grid), facilitating seamless integration into modular optomechanical platforms.

Key Features

• Two orthogonal adjustment axes (pitch and yaw) with independent, lockable micrometer drives
• High-stability monolithic base constructed from 304 stainless steel with precision-machined kinematic interfaces
• Dual-stage locking mechanism: coarse pre-load lock + fine-position retention screw for vibration-resistant holding
• Three interchangeable clamping configurations supporting Ø38.1 mm, Ø50 mm, and Ø50.8 mm optics—each optimized for minimal stress-induced wavefront distortion
• Clear apertures of 35 mm (for 38.1 mm mount) and 47 mm (for 50 mm and 50.8 mm variants), preserving usable beam area while accommodating standard mirror substrates
• Angular adjustment range of ±3° per axis, calibrated to ≤0.5 arcmin repeatability after 500 adjustment cycles
• Black anodized aluminum top plate and stainless steel hardware for corrosion resistance and non-magnetic compatibility in sensitive environments

Sample Compatibility & Compliance

The OMRS38.1/50/50.8-CS accommodates standard optical components including dielectric mirrors, metallic-coated substrates, polarizing cubes, and thin-film filters with thicknesses ranging from 3 mm to 12 mm. Each variant includes adjustable retaining rings with elastomeric gasket inserts to prevent edge chipping and minimize radial stress gradients across the optic surface. The mount meets mechanical interface requirements specified in ISO 10110-7 (optical component mounting tolerances) and supports alignment workflows compliant with ISO/IEC 17025 calibration laboratory practices. While not certified to specific regulatory standards (e.g., FDA or CE for medical devices), its construction adheres to general-purpose laboratory equipment safety guidelines per IEC 61010-1, including mechanical stability testing at 5 g acceleration and thermal drift characterization from 15 °C to 30 °C.

Software & Data Management

This is a purely manual, hardware-only optical mount with no embedded electronics, firmware, or software dependencies. All adjustments are performed via tactile micrometer knobs with engraved angular scales (0.1° increments) and vernier-assisted readouts. For traceable alignment documentation, users may integrate the mount into digital lab notebooks (e.g., LabArchives, Benchling) or metrology software suites (e.g., Thorlabs Kinesis, Newport Motion Control SDK) using external position-sensing accessories such as capacitive displacement sensors or autocollimators. Audit trails for alignment history can be maintained through version-controlled experiment logs, satisfying GLP-aligned documentation requirements where instrument setup parameters must be recorded and retrievable.

Applications

• Precision alignment of laser cavities in Ti:sapphire, fiber, and diode-pumped solid-state lasers
• Stabilization of interferometer arms in Michelson, Mach–Zehnder, and Fabry–Pérot configurations
• Beam path correction and pointing stabilization in ultrafast pump-probe spectroscopy systems
• Integration into vacuum-compatible optical tables (with optional vacuum-rated hardware kits)
• Education and training platforms for undergraduate optics laboratories requiring repeatable, hands-on alignment exercises
• Custom OEM subsystems where compact footprint (< 85 × 85 × 50 mm), low mass (< 420 g), and deterministic adjustment behavior are prioritized

FAQ

What optical substrate thicknesses are supported by the OMRS series?
Standard configurations accommodate substrates from 3 mm to 12 mm thick; custom retaining ring sets are available for thinner ( 15 mm) optics upon request.
Is vacuum compatibility available?
Yes—vacuum-rated versions (UHV compatible to 1×10⁻⁸ mbar) are offered with stainless steel fasteners, vacuum-compatible lubricants, and outgassing-tested materials; lead time increases by 3–4 weeks.
Can this mount be motorized?
ZOLIX does not supply integrated motorized actuators for the OMRS platform; however, third-party stepper motor couplers (e.g., OptoSigma MCM series) can be retrofitted using the standard 4-40 UNC micrometer shaft interface.
What is the maximum recommended optic weight?
For optimal angular stability and repeatability, the mount is rated for optics up to 250 g; heavier loads may be supported with reduced adjustment resolution and increased settling time.
Are replacement parts available separately?
Yes—individual components including micrometer assemblies, retaining rings, base plates, and locking screws are stocked and available under ZOLIX part numbers with full dimensional drawings and RoHS compliance documentation.
