Overview
The HTMM25-03 Beam Steering Mirror Mount is a precision-engineered optical mounting solution designed for stable, repeatable angular alignment of reflective optics in laboratory and industrial optical setups. Built upon a rigid aluminum alloy base with black anodized finish, this kinematic mount employs a three-point contact adjustment system—two differential micrometer screws (M4 × 0.25 pitch) and one fixed pivot point—to enable fine-tuned tip/tilt control of mounted mirrors with sub-milliradian resolution. Its core function relies on mechanical stability under thermal drift and vibration, ensuring long-term beam path fidelity in interferometry, laser cavity alignment, spectroscopic beam routing, and free-space optical communication test benches. Unlike passive mounts, the HTMM25-03 integrates calibrated angular feedback capability through optional encoder-equipped actuators (sold separately), supporting traceable alignment protocols required in ISO/IEC 17025-accredited metrology labs.
Key Features
- Compatible with standard optical mirrors up to Ø25.4 mm (1 inch) and Ø25 mm, accommodating both metric and imperial diameter standards without adapter rings
- Adjustment range: ±3° tip and tilt (±1.5° per axis), with 10 µm per division resolution on integrated vernier scales
- Mounting base features four M6 threaded holes (25 mm spacing) and dual 12 mm wide T-slots for modular integration onto optical tables or breadboards
- Stainless steel adjustment screws with brass bushings minimize hysteresis and backlash; locking nuts provide secure position retention during transport or environmental cycling
- Surface flatness tolerance of ≤0.5 µm over the mirror contact zone ensures minimal wavefront distortion (<λ/10 @ 633 nm) when used with λ/20 or better mirrors
- RoHS-compliant construction; no outgassing materials used—suitable for vacuum-compatible configurations (up to 10⁻⁴ Pa with optional vacuum-rated hardware)
Sample Compatibility & Compliance
The HTMM25-03 supports dielectric-coated, metallic (Al, Au), and protected silver mirrors with thicknesses from 3 mm to 12 mm. It complies with mechanical interface standards defined in ISO 10110-7 (optical element mounting) and aligns with dimensional conventions referenced in Thorlabs’ and Newport’s universal mount ecosystems. While not certified to specific electromagnetic compatibility (EMC) or safety directives (e.g., CE, UKCA), its passive mechanical design meets general-purpose lab equipment requirements under IEC 61000-6-2 (immunity) and IEC 61000-6-3 (emissions) when installed within shielded optical enclosures. For GLP/GMP-regulated environments, full traceability documentation—including material certificates (EN 10204 3.1), surface roughness reports (Ra < 0.8 µm), and dimensional inspection records—is available upon request.
Software & Data Management
As a purely mechanical mount, the HTMM25-03 does not incorporate embedded electronics or firmware. However, it is fully compatible with third-party motion control platforms such as Thorlabs Kinesis®, Newport Motion Control Software, or LabVIEW-based alignment automation systems via external motorized actuators (e.g., Zaber T-NA series linear stages interfaced with mirror carriers). When integrated into automated beam-steering systems, positional data can be logged with timestamped metadata compliant with FDA 21 CFR Part 11 requirements using validated SCADA or LIMS interfaces. Calibration logs, adjustment history, and maintenance records are managed externally in accordance with ISO/IEC 17025 clause 7.7 (equipment management).
Applications

- Beam path stabilization in Raman spectroscopy systems requiring multi-channel spectral routing
- Alignment of reference arms in Michelson and Mach–Zehnder interferometers
- Dynamic wavefront correction pre-stages in adaptive optics testbeds using segmented deformable mirrors
- Teaching laboratories for undergraduate optics courses covering ray matrix formalism and Gaussian beam propagation
- Integration into OEM photonic assembly stations for telecom transceiver calibration and coupling efficiency testing
FAQ
What mirror thicknesses are supported?
Mirrors between 3 mm and 12 mm thick can be securely clamped without deformation or edge stress.
Is thermal drift compensated in the design?
No active compensation is built-in; however, the low-CTE aluminum alloy (6061-T6) and symmetric geometry reduce thermally induced misalignment to <5 µrad/°C over 15–35 °C ambient range.
Can this mount be used in ultra-high vacuum (UHV) environments?
Standard configuration is rated for high vacuum (10⁻⁴ Pa); UHV use requires optional vacuum-compatible lubricants and stainless steel fasteners (part number HTMM25-03-VAC).
Does it include alignment targets or fiducial marks?
Yes—a crosshair-engraved reference reticle is laser-marked on the base plate adjacent to the mirror centerline for rapid visual co-alignment.
Are replacement screws or custom-threaded variants available?
M4 × 0.25, M3 × 0.5, and 8-32 UNC screw kits are stocked; custom thread pitches or non-standard lengths can be ordered with lead time of 4–6 weeks.
