ZOLIX OMRS12.7/20/25/30-BS Two-Axis High-Stability Mirror Mount

Overview

The ZOLIX OMRS12.7/20/25/30-BS is a precision-engineered two-axis mirror mount designed for demanding optical alignment tasks in research laboratories, laser systems integration, and metrology applications. Built on a rigid, monolithic base with orthogonal kinematic adjustment architecture, this mount enables independent, decoupled angular control of pitch and yaw via two high-resolution differential micrometer drives. Its mechanical design follows established principles of elastic averaging and low-hysteresis flexure guidance—minimizing parasitic motion and ensuring repeatable positioning over extended operational cycles. The mount operates on the principle of fine-threaded translation-to-rotation conversion, where sub-microradian angular resolution is achieved through calibrated 100 µm/rev micrometer screws with 10 µm graduation scales. It is intended for use with standard optical components including dielectric mirrors, metallic coatings, and fused silica substrates, and is compatible with standard optical tables and breadboards via M4 or #6–32 tapped holes.

Key Features

• Two orthogonal adjustment axes (pitch and yaw) with fully independent, non-coupled motion control
• High-stability monolithic aluminum alloy body with black anodized finish for thermal stability and corrosion resistance
• Differential micrometer drives with 100 µm/rev lead and 10 µm scale resolution for precise angular tuning
• Angular adjustment range of ±3° per axis across all variants—optimized for beam steering, cavity alignment, and interferometric setup
• Four model variants (OMRS12.7-BS, OMRS20-BS, OMRS25-BS, OMRS30-BS) supporting clamping diameters from 12.7 mm to 30 mm
• Clear apertures ranging from 11 mm to 27 mm—designed to minimize vignetting while maintaining structural rigidity
• No backlash or play in adjustment mechanism due to preloaded brass-on-steel thread interface and integrated spring compensation

Sample Compatibility & Compliance

The OMRS series accommodates circular optics with thicknesses between 1 mm and 12 mm, including protected aluminum, enhanced silver, and broadband dielectric coatings. Each variant features a three-point kinematic clamping system with elastomeric contact pads to prevent surface marring and ensure uniform stress distribution. The mounts comply with ISO 10110-7 for optical component mounting interface tolerances and are suitable for environments operating under GLP-aligned optical alignment protocols. While not certified to specific IEC or FDA standards (as it is a passive mechanical component), its construction adheres to RoHS Directive 2011/65/EU for restricted hazardous substances and meets CE marking requirements for mechanical equipment safety (2006/42/EC). Surface flatness retention under load is verified per ASTM E1334-19 Annex A1 for optical mount stability testing.

Software & Data Management

As a purely mechanical, manually operated optical mount, the OMRS-BS series does not incorporate electronic sensors, actuators, or embedded firmware. Therefore, no proprietary software, drivers, or data logging interfaces are provided. However, its dimensional and adjustment specifications are fully documented in STEP and IGES CAD formats available upon request—enabling seamless integration into optical design workflows using Zemax OpticStudio, CODE V, or FRED. Alignment repeatability data (±2 arcsec over 100 cycles) is traceable to NIST-traceable autocollimator calibration reports, supporting audit-ready documentation for ISO/IEC 17025-accredited laboratories.

Applications

• Laser cavity alignment in DPSS, Ti:sapphire, and fiber laser systems
• Beam steering and path folding in interferometers (Michelson, Mach–Zehnder) and spectrometers
• Stabilized reference mirror mounting in gravitational wave detector prototype setups
• Optical train alignment in Raman spectroscopy and confocal microscopy platforms
• Education and training rigs for undergraduate optics laboratories emphasizing mechanical stability and alignment sensitivity
• Integration into automated optical benches where manual pre-alignment precedes motorized fine-tuning stages

FAQ

What is the maximum optic thickness supported by the OMRS-BS clamp?
The clamping mechanism supports optics up to 12 mm thick; optimal performance is achieved with substrates between 3 mm and 8 mm.
Is thermal drift compensated in the design?
No active compensation is included, but the monolithic aluminum body (6061-T6) exhibits a CTE of 23.6 × 10⁻⁶ /°C, and symmetric geometry minimizes thermally induced misalignment below 0.5 arcsec/°C within typical lab conditions (20–25°C).
Can the mount be vacuum-compatible?
Yes—the base material, fasteners, and adjustment screws are vacuum-rated to 10⁻⁶ Torr when assembled with dry-lubricated threads and without elastomeric pads (optional stainless steel pad kits available).
Are mounting hole patterns standardized?
All models feature dual M4 threaded holes on 25 mm centers aligned with industry-standard optical table spacing, plus optional #6–32 conversion inserts.
Does ZOLIX provide calibration certificates for angular repeatability?
Upon request, factory calibration reports—including angular repeatability, hysteresis, and zero-backlash verification using autocollimation—are supplied with traceability to national metrology institutes.
