Overview
The HTAC-PS-03 Cross Rod Mount is a precision-engineered optical mounting component designed for stable, repeatable alignment of cylindrical optical elements—such as lenses, filters, or light guides—in orthogonal configurations. Constructed from high-grade anodized aluminum alloy, it features two mutually perpendicular through-holes, each with a nominal bore diameter of 12.5 mm, conforming to the widely adopted standard for Ø12.5 mm optical rods and posts in laboratory and OEM optical systems. Its low-mass architecture (0.04 kg) minimizes mechanical inertia and thermal drift while maintaining structural rigidity under typical lab-grade loading conditions. Unlike kinematic or flexure-based mounts, this cross mount operates on a passive, rigid-body principle—relying on precise hole location tolerance and surface flatness rather than adjustable degrees of freedom—making it ideal for fixed-axis beam routing, multi-stage optical benches, and modular optomechanical assemblies where long-term positional stability is prioritized over real-time adjustment.
Key Features
- Two orthogonal, precision-drilled through-holes (Ø12.5 mm ±0.02 mm), aligned to ≤1 arcmin angular deviation relative to each other
- Optimized for compatibility with industry-standard Ø12.5 mm stainless steel or aluminum rods (e.g., Thorlabs TR series, Newport U100 series)
- Anodized aluminum body (6061-T6) offering corrosion resistance, non-magnetic operation, and low thermal expansion coefficient (~23.6 µm/m·K)
- Minimal mass design (40 g) reduces vibration coupling and facilitates integration into compact or weight-sensitive optical platforms
- Flat, ground base surface (Ra ≤0.8 µm) ensures consistent contact with breadboards, optical tables, or custom mounting plates
- No moving parts or locking mechanisms—engineered for zero-backlash, maintenance-free operation over extended service life
Sample Compatibility & Compliance
The HTAC-PS-03 is compatible with any cylindrical optical component or mechanical rod that conforms to the ISO 10110-7 and DIN 476 standard for Ø12.5 mm nominal diameter components. It supports static load capacities up to 5 kg per axis when mounted using M4 or #8–32 cap screws on a rigid substrate. While not certified to ISO 9001 or EN 15038 individually (as a passive mechanical part), its dimensional tolerances and material specifications align with common quality control practices referenced in ISO/IEC 17025-accredited optical calibration laboratories. The mount complies with RoHS 2011/65/EU directives regarding hazardous substances and contains no lead, cadmium, or hexavalent chromium in its anodized finish or base alloy.
Software & Data Management
As a purely mechanical mounting solution, the HTAC-PS-03 requires no firmware, drivers, or software interface. It does not generate telemetry, position feedback, or digital logs. However, its dimensional repeatability and geometric fidelity support traceable optical system modeling in third-party ray-tracing environments—including Zemax OpticStudio, FRED, or CODE V—where accurate physical constraints (e.g., hole center-to-center distance: 32.0 mm ±0.05 mm; bore axis orthogonality) are imported as fixed parameters. When used in GLP/GMP-regulated setups (e.g., laser safety interlock paths or metrology chain alignment), its passive nature eliminates validation requirements associated with electronic actuators or motorized stages.
Applications
- Stabilizing orthogonal beam paths in interferometric setups (e.g., Mach–Zehnder or Michelson configurations)
- Mounting collimating lens pairs in fiber-coupling stations requiring fixed spatial separation and angular registration
- Serving as a junction node in multi-axis optomechanical frames for UV–VIS spectrophotometers or fluorescence imaging systems
- Integration into educational optics kits where robustness, clarity of geometry, and ease of assembly are pedagogically essential
- Supporting alignment fixtures in laser cavity construction, particularly for diode-pumped solid-state (DPSS) lasers with folded resonator geometries
FAQ
What materials are used in the construction of the HTAC-PS-03?
The mount is fabricated from 6061-T6 aluminum alloy and finished with a hard-anodized coating (Type II, 15–25 µm thickness) for enhanced surface hardness and environmental resistance.
Is the 12.5 mm bore dimension metric or imperial?
It is a metric specification, fully aligned with ISO 10110-7 and commonly referenced in both European and North American optical catalogs as the standard “½-inch” equivalent (actual diameter = 12.7 mm is imperial; 12.5 mm is distinct and widely adopted in precision Chinese and Japanese optical hardware).
Can this mount be used in vacuum environments?
Yes—provided outgassing is mitigated via pre-baking at 120 °C for 2 hours; the anodized layer is stable under UHV conditions (<1×10⁻⁷ mbar), though secondary electron emission characteristics should be verified for charged-particle applications.
Are mounting screws included with the HTAC-PS-03?
No—standard M4×0.7 or #8–32 socket head cap screws are recommended for secure attachment; torque specification: 1.2–1.5 N·m to avoid thread deformation.
Does Han Ding provide dimensional inspection reports for batch orders?
Upon request and subject to minimum order quantity (MOQ ≥50 units), Han Ding can supply CMM-measured conformance reports per ASME Y14.5-2018 GD&T standards, including bore concentricity, orthogonality, and base flatness verification.
