OM01-GA15 Reflective/Beam-Splitting Mirror Mount

Overview

The OM01-GA15 Reflective/Beam-Splitting Mirror Mount is a precision-engineered optical adjustment component designed for stable, repeatable angular alignment of mirrors and beam splitters in laboratory, metrology, and industrial optical systems. Based on a robust enclosed mechanical architecture, it employs a ring-clamping mechanism to secure optical elements within the mount’s cylindrical tube—ensuring minimal stress-induced distortion and long-term positional stability. Angular positioning is achieved via two orthogonal micrometer-driven adjustment screws acting on a kinematic base, enabling fine-tuned single-axis tilt control up to ±4° with high mechanical reproducibility. The mount integrates a high-cycle-life disc spring return system that maintains consistent pre-load across thermal and vibrational conditions—critical for maintaining alignment integrity during extended operation or environmental fluctuations. Its compact footprint (15 mm clear aperture), low mass (0.1 kg), and standardized mounting interface make it suitable for integration into multi-element optical benches, laser cavities, interferometric setups, and OEM optomechanical subsystems.

Key Features

• Enclosed structural design minimizes dust ingress and protects internal adjustment mechanisms from mechanical damage.
• Ring-clamp retention system secures optics without direct contact to reflective surfaces—preserving coating integrity and avoiding edge chipping.
• Precision-machined disc spring assembly delivers uniform, hysteresis-minimized return force for reliable zero-point repeatability after repeated adjustments.
• Standardized mounting pattern: 2×M6 through-holes for rigid base attachment and 4×M4 tapped holes for auxiliary bracket or adapter integration.
• Optimized thermal mass distribution and aluminum alloy construction (6061-T6 equivalent) ensure dimensional stability over ambient temperature ranges (15–30 °C).
• Interchangeable compatibility with PH-series post holders, BP-series base plates, magnetic bases, threaded adapter screws, and ring wrench tools—enabling modular optical train configuration.

Sample Compatibility & Compliance

The OM01-GA15 is optimized for plano or slightly curved mirrors and beam splitters with 15 mm clear aperture and standard 1 mm or 2 mm thickness (e.g., BK7, fused silica, or coated dielectric substrates). It complies with ISO 10110-7 (optical element mounting interfaces) and adheres to mechanical tolerancing standards per ISO 2768-mK. While not an active measurement instrument, its dimensional repeatability supports traceable alignment workflows compliant with ISO/IEC 17025-accredited calibration laboratories when used in conjunction with autocollimators or position-sensing detectors. No electrical or laser safety certification (e.g., IEC 60825-1) applies, as the mount itself contains no powered components.

Software & Data Management

This is a passive optomechanical component; no embedded firmware, software drivers, or digital data interfaces are included. Alignment parameters—including angular offset, torque settings, and mounting orientation—are documented manually or integrated into lab notebook systems (e.g., LabArchives, Benchling) using standardized metadata templates aligned with GLP documentation practices. For automated alignment systems, the OM01-GA15 may be paired with external motorized actuators (e.g., Thorlabs K10CR1-compatible stages) and controlled via ASCII-based serial protocols or LabVIEW-compatible DAQ modules—though such integration falls outside the scope of the mount’s native functionality.

Applications

• Laser cavity mirror alignment in CW and pulsed DPSS laser systems.
• Beam steering and path folding in FTIR spectrometers and Raman probe heads.
• Reference mirror mounting in Michelson and Mach-Zehnder interferometers.
• Alignment-critical coupling of free-space optics into fiber collimators or photonic integrated circuits.
• Modular optical test benches for university teaching labs and R&D prototyping environments.
• OEM integration into medical imaging devices requiring stable, serviceable mirror positioning (e.g., endomicroscopy illumination paths).

FAQ

What optical substrate thicknesses are supported by the OM01-GA15?

Standard compatibility includes 1 mm and 2 mm thick optics; custom spacers or retaining rings may extend support to 0.5–3 mm thicknesses upon request.
Is thermal drift compensated in this mount?

No active compensation is provided; however, the aluminum alloy body and symmetrical clamping geometry minimize differential expansion effects, yielding angular drift below 3 arcsec/°C under controlled lab conditions.
Can this mount be used in vacuum environments?

Yes—when assembled with vacuum-rated lubricants (e.g., Braycote 601 EF) and non-outgassing fasteners, it meets ISO 14644 Class 5 cleanroom and UHV-compatible mechanical handling requirements.
Does the disc spring require periodic replacement?

Under normal use (≤10⁴ adjustment cycles), the spring retains >95% of initial load capacity; replacement kits (part #SP-OM01-DISC) are available for preventive maintenance schedules.
Are CAD models available for integration into optical design software?

STEP and IGES files compliant with Zemax OpticStudio, CODE V, and SolidWorks are provided free of charge upon distributor registration and NDA execution.
