HTMM50 Base-Mounted Reflective/Beam-Splitting Mirror Mount, 50 mm Clamp Diameter

Overview

The HTMM50 Base-Mounted Reflective/Beam-Splitting Mirror Mount is a precision optical mounting solution engineered for stable, repeatable alignment of reflective and beam-splitting optics in laboratory and industrial optical setups. Designed around a rigid base-plate architecture with integrated kinematic adjustment capability, the mount employs a three-point contact configuration—two lateral micrometer-driven push screws and one central spring-loaded pull screw—to enable high-resolution angular control over pitch and yaw axes. Its core function is to secure circular optics up to 50 mm in diameter while maintaining minimal stress-induced wavefront distortion, making it suitable for interferometric, spectroscopic, and laser cavity alignment applications where beam pointing stability and long-term positional retention are critical.

Key Features

• Optimized mechanical design featuring a solid aluminum alloy base with black anodized finish for enhanced rigidity and corrosion resistance.
• Clamping mechanism accommodates optics with diameters precisely up to 50 mm; compatible with standard Ø50 mm mirrors, beamsplitters, and pellicles.
• Two independent 0.5 mm pitch micrometer screws provide fine angular adjustment with tactile feedback and sub-arcminute resolution under controlled loading conditions.
• Integrated locking system allows secure fixation after alignment without drift, supporting both static and quasi-dynamic optical configurations.
• Mounting footprint includes standard M4 and M6 threaded holes on the base plate for compatibility with optical tables, breadboards, and translation stages.
• No internal magnetic components—ensures suitability for environments sensitive to stray fields, including ultrafast laser labs and quantum optics experiments.

Sample Compatibility & Compliance

The HTMM50 supports plano and wedged substrates made from fused silica, BK7, CaF₂, and coated dielectric or metallic mirror surfaces. It complies with general mechanical handling standards for optical components per ISO 10110-7 (surface imperfections) and ANSI/OEOSC OP1.002 (optical mount dimensional tolerances). While not certified to specific regulatory frameworks such as FDA or CE for medical or safety-critical use, its construction adheres to widely accepted laboratory-grade mechanical integrity benchmarks used across academic research facilities and R&D centers operating under GLP-aligned protocols. The absence of adhesives or elastomeric interfaces ensures full traceability and avoids outgassing concerns in vacuum-compatible variants (when paired with compatible base plates).

Software & Data Management

This is a purely mechanical optical mount with no embedded electronics, firmware, or digital interface. Alignment data—including angular settings, torque values, and positional history—is maintained manually via lab notebooks or integrated into institutional electronic lab notebook (ELN) systems such as LabArchives or Benchling. Users may log calibration records, maintenance logs, and usage metadata in accordance with internal quality assurance procedures. For laboratories operating under 21 CFR Part 11 requirements, manual entry into validated ELN platforms satisfies audit-trail and signature integrity mandates when combined with appropriate access controls and versioning policies.

Applications

• Laser cavity mirror alignment in CW and pulsed solid-state, fiber, and diode laser systems.
• Beam steering and path folding in FTIR, Raman, and UV-Vis spectrometers.
• Interferometer arm stabilization in Michelson, Mach–Zehnder, and Twyman–Green configurations.
• Integration into custom optical assemblies requiring modular, field-serviceable mirror positioning.
• Educational optics labs where reproducible setup repeatability supports pedagogical consistency across student cohorts.
• Alignment of dichroic filters and broadband beamsplitters in multi-wavelength imaging and fluorescence microscopy systems.

FAQ

What is the maximum optic thickness supported by the HTMM50 clamp?
The mount accepts optics up to 12 mm thick when using standard retaining rings; thicker substrates may require custom spacers or alternative clamping hardware.
Is thermal drift compensated in this design?
No active thermal compensation is incorporated; however, the low-CTE aluminum alloy base and symmetric adjustment geometry minimize thermally induced misalignment under ambient lab conditions (±2°C fluctuation).
Can this mount be used in vacuum environments?
Yes—when assembled with vacuum-rated fasteners and compatible non-outgassing lubricants, the HTMM50 has been deployed in UHV-compatible optical benches at pressures down to 1×10⁻⁷ mbar.
Does the manufacturer supply alignment certification or test reports?
HanDing provides dimensional inspection reports upon request; full angular repeatability or wavefront distortion characterization requires third-party metrology and is not included in standard delivery.
Are replacement parts (e.g., micrometer screws, retaining rings) available separately?
Yes—standard M4×0.5 micrometer screws, stainless steel retaining rings, and base-plate mounting kits are stocked and orderable under part numbers HT-MM50-SCREW, HT-MM50-RING, and HT-MM50-BASEKIT respectively.
