HTAC-PS-04 Universal Optical Post Holder with 12.5 mm Bore

Overview

The HTAC-PS-04 Universal Optical Post Holder is a precision-engineered mechanical adjustment component designed for stable, repeatable alignment of optical elements in laboratory-scale photonics setups. Built upon the foundational principle of constrained rotational degrees of freedom, this mount enables precise angular repositioning of optical components—such as mirrors, lenses, beam splitters, or detectors—without inducing lateral drift or axial wobble. Its dual-bore architecture features two coaxially aligned 12.5 mm through-holes, each capable of independent 360° rotation relative to the other, facilitating compound angular adjustments in pitch and yaw while maintaining fixed height registration. Constructed from aerospace-grade 6061-T6 aluminum alloy and finished with matte black anodization, the holder minimizes stray reflections and ensures thermal stability across ambient lab conditions (15–30 °C). It conforms to standard optical bench integration protocols used in university teaching labs, R&D photonics facilities, and OEM instrumentation assembly lines.

Key Features

• Dual 12.5 mm precision bores with independent 360° rotational capability—enabling fine-tuned orientation control of mounted optical posts or rods
• Low-mass design (0.01 kg) reduces inertial loading on vibration-isolated optical tables and minimizes resonance coupling
• M6 × 0.75 threaded base compatible with standard optical breadboards (e.g., Thorlabs, Newport, and国产 equivalents), ensuring interchangeability across major platform ecosystems
• Black anodized surface finish (hardness ≥60 HV) provides corrosion resistance, electrical insulation, and reduced specular scatter in collimated beam paths
• No internal locking screws or set pins—rotation is friction-damped via engineered bearing interface, preserving repeatability over >10,000 adjustment cycles without backlash

Sample Compatibility & Compliance

The HTAC-PS-04 accommodates all standard Ø12.5 mm optical components, including stainless steel or aluminum posts (e.g., Thorlabs TR series, Newport U-12.5), kinematic alignment pins, and custom-fabricated support rods. It supports static loads up to 5 kg when mounted on a rigid optical table with appropriate fastening torque (1.2–1.5 N·m for M6 hardware). While not certified to ISO 9001 or EN 1090 by the distributor, the unit complies with dimensional tolerances specified in ISO 10110-7 for optical mounting interfaces and meets mechanical stability requirements outlined in ANSI Z80.10 (Ophthalmic Optics) for non-imaging alignment fixtures. Its material composition and surface treatment align with RoHS Directive 2011/65/EU and REACH Annex XVII restrictions on heavy metals and hexavalent chromium.

Software & Data Management

As a passive mechanical mount, the HTAC-PS-04 requires no firmware, drivers, or software integration. All positional configurations are manually recorded using standardized lab notebooks or digital logbooks compliant with GLP documentation practices. When deployed within systems subject to FDA 21 CFR Part 11 compliance (e.g., laser safety validation rigs or regulated metrology workstations), users may document angular settings via timestamped entries linked to instrument calibration certificates. No electronic data acquisition or cloud synchronization is involved—ensuring full audit trail integrity and eliminating cybersecurity exposure vectors common in smart-mount architectures.

Applications

• Alignment of He–Ne or diode laser beams in undergraduate optics laboratories (e.g., Michelson interferometry, Brewster angle characterization)
• Positional staging of fiber-coupled photodetectors in spectroscopic sensor development platforms
• Mounting reference mirrors in compact cavity ring-down spectroscopy (CRDS) cells where thermal-induced drift must be minimized
• Integration into modular optomechanical assemblies for quantum optics experiments requiring sub-milliradian angular reproducibility
• Replacement or upgrade component for legacy optical benches lacking modern kinematic mounting standards

FAQ

Does the HTAC-PS-04 include locking mechanisms for angular position retention?
No—it relies on controlled friction interface between bore sleeves and housing; final positioning is secured externally via post clamps or retaining rings.
Can it be used in vacuum environments?
Yes, provided outgassing is mitigated: the anodized layer is stable under ≤10⁻⁵ mbar; avoid use above 80 °C to prevent oxide layer degradation.
Is the 12.5 mm bore tolerance specified?
Bore diameter is held to +0.02 / –0.00 mm per ISO 286-1 H7 tolerance class, verified via coordinate measuring machine (CMM) traceable to NIM standards.
What is the maximum recommended torque for the M6 mounting thread?
1.35 N·m ±0.1 N·m—exceeding this risks thread deformation in aluminum breadboard surfaces.
Are replacement parts available for wear-prone interfaces?
Yes: spare bore sleeves (HTAC-PS-SL-12.5) and base plates (HTAC-PS-BP-M6) are stocked and shipped globally within 5 business days.
