Hanting HTRA10 1000 mm Precision Linear Optical Translation Rail

Overview

The Hanting HTRA10 is a high-stability, precision-engineered linear translation rail designed for demanding optical alignment tasks in research-grade laboratories and industrial R&D environments. Constructed from aerospace-grade 6061-T6 aluminum alloy and finished with hard-anodized surface treatment (Type II, 25 µm thickness), the rail delivers exceptional dimensional stability, corrosion resistance, and long-term mechanical integrity under repeated load cycling. Its fundamental function is to provide a rigid, repeatable, and co-axial mechanical reference axis—enabling precise spatial registration of multiple optical components such as mirrors, lenses, beam splitters, and detectors within a single optical train. The rail operates on passive mechanical translation principles: no motorization or actuation is integrated; instead, it serves as a passive platform for manual or externally driven positioning stages (e.g., micrometer-driven carriers or motorized carriages mounted atop). This architecture ensures zero electromagnetic interference (EMI), thermal drift minimization via low-coefficient-of-thermal-expansion (CTE ≈ 23.6 × 10⁻⁶ /°C) material selection, and compatibility with vacuum-compatible configurations when paired with appropriate accessories.

Key Features

• 1000 mm nominal length with ±0.05 mm dimensional tolerance across full span, verified per ISO 2768-mK general tolerances
• Top-mounted precision-machined dovetail interface (8 mm width, 60° angle) engineered for repeatable, backlash-free engagement with HTAC-RC series carrier stages
• Integrated engraved metric scale (0–1000 mm), laser-marked at 1 mm intervals with 0.5 mm interpolation marks for visual positional estimation
• Four M4 threaded mounting holes (2 per end) spaced at standardized 25 mm intervals, compliant with common optical breadboard hole patterns (e.g., Thorlabs, Newport)
• Surface roughness Ra ≤ 0.8 µm on functional rails and dovetail surfaces, ensuring low-friction sliding performance with compatible carriers
• Flatness tolerance ≤ 15 µm over full length, measured per ISO 1101 using coordinate measuring machine (CMM) traceable to NIM standards

Sample Compatibility & Compliance

The HTRA10 rail is inherently component-agnostic—it does not interact optically or electronically with samples but functions as a foundational mechanical substrate for optical assemblies. It supports standard Ø12.7 mm, Ø25.4 mm, and Ø50.8 mm lens mounts, kinematic mirror mounts (e.g., KM100 series), and translation stages with dovetail receivers. All materials comply with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. While the rail itself carries no CE marking (as it is a passive mechanical component), its design adheres to mechanical safety principles outlined in ISO 12100:2010. For GLP/GMP-regulated optical alignment workflows—such as laser cavity setup in pharmaceutical analytical instrumentation or interferometric calibration labs—the rail’s dimensional traceability, surface finish consistency, and batch documentation support audit readiness.

Software & Data Management

As a purely mechanical positioning platform, the HTRA10 requires no firmware, drivers, or proprietary software. Positional data acquisition is performed externally via calibrated digital calipers, laser displacement sensors (e.g., Keyence LK-G series), or vision-based metrology systems. When integrated into automated setups (e.g., motorized carriage + Arduino/Raspberry Pi controller), position feedback may be logged via open-protocol interfaces (UART, I²C, or analog voltage output). No data encryption, user authentication, or 21 CFR Part 11 compliance features are applicable—consistent with ISO/IEC 17025:2017 guidance for passive metrological artifacts.

Applications

• Coaxial alignment of multi-element laser resonators (e.g., Ti:sapphire oscillator-amplifier chains)
• Staging platforms for optical coherence tomography (OCT) sample arms requiring sub-10 µm repeatability
• Base rails in custom-built spectrometer slit alignment fixtures and monochromator calibration rigs
• Modular optical benches for undergraduate physics labs (e.g., Michelson interferometry, Fourier optics experiments)
• Mounting backbone for transient absorption spectroscopy pump-probe delay lines
• Integration into ISO-classified cleanroom optical assembly stations where non-outgassing, particle-free surfaces are mandatory

FAQ

Is the HTRA10 compatible with Thorlabs or Newport dovetail carriers?

Yes—its 8 mm wide, 60° angled dovetail conforms to ANSI/ISO 8015 geometric tolerancing standards and has been empirically verified for mechanical interchangeability with Thorlabs PT1/M and Newport UMB12 carriers. Minor fit variation (< 5 µm clearance) may occur due to vendor-specific manufacturing allowances.

Can the rail be used in vacuum environments?

The base anodized aluminum construction is vacuum-compatible up to 10⁻⁵ mbar when cleaned per ASTM E2497-06. However, users must verify compatibility of attached accessories (e.g., adhesives, lubricants) separately.

What is the maximum recommended load capacity?

Static load limit is 8 kg uniformly distributed; dynamic load limit (with carrier motion) is 3 kg to maintain ≤ 2 µm deflection at mid-span, per finite element analysis (FEA) validation report available upon request.

Does the engraved scale require recalibration?

No—the scale is mechanically engraved during final machining and is traceable to national length standards. It does not drift with time or temperature under normal lab conditions (20 ± 2 °C, 40–60% RH).
