Hanting HTAC-RC-03 Precision Linear Translation Stage for Optical Alignment

Overview

The Hanting HTAC-RC-03 Precision Linear Translation Stage is a manually operated, high-stability optical mounting platform engineered for sub-millimeter positional repeatability in demanding optical alignment applications. Designed according to standard kinematic principles, it employs a hardened stainless steel base, precision-ground linear bearing rails, and a fine-pitch brass-steel micrometer drive mechanism (10 µm per graduation) to deliver controlled uniaxial displacement with minimal wobble or tilt error. Its modular dovetail interface (8 mm groove width, ISO 9001-compliant machining tolerances) ensures compatibility with industry-standard optical posts, cage systems, and breadboard-mounted setups. The stage operates on the principle of mechanical translation via differential screw actuation—eliminating backlash through preloaded anti-backlash nut design—and is optimized for use in laser beam steering, interferometric path-length adjustment, fiber coupling alignment, and spectroscopic sample positioning where thermal drift stability and mechanical hysteresis are critical performance constraints.

Key Features

• Travel range: 13 mm with ±0.5 µm repeatability under 2 N axial load (verified per ISO 230-2 Annex B)
• Low-profile form factor: 42 mm × 60 mm × 18 mm footprint; compatible with stacked multi-axis configurations
• Black anodized aluminum body with corrosion-resistant surface finish (ASTM B557-18 compliant)
• Integrated locking screw (M3 thread) for position retention during vibration-prone operation
• Optical-grade surface flatness: ≤1.5 µm over full travel (measured by Zygo NewView 7300 interferometer)
• No lubrication required; dry-running PTFE-coated lead screw ensures clean-room suitability (ISO Class 5 compatible)

Sample Compatibility & Compliance

The HTAC-RC-03 is designed for integration into optical assemblies requiring passive, non-powered motion control—particularly in university teaching labs, metrology calibration environments, and R&D prototyping rigs. It supports standard Ø25.4 mm optical components (lenses, mirrors, filters) when mounted via compatible SM1-threaded adapters or kinematic clamps. All structural materials comply with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Mechanical specifications adhere to ISO 10110-7 (surface imperfection tolerancing) and DIN 3185 (micrometer drive accuracy classification). While not certified for medical or aerospace-grade qualification, its dimensional stability (±0.8 µm/°C thermal coefficient) meets typical requirements for GLP-aligned optical characterization workflows.

Software & Data Management

As a purely manual mechanical stage, the HTAC-RC-03 does not incorporate embedded electronics, sensors, or digital interfaces. It requires no firmware, drivers, or software configuration. Position tracking must be performed externally using calibrated imaging systems (e.g., CCD-based beam profiling), laser interferometers, or coordinate measuring machines. For laboratories operating under FDA 21 CFR Part 11 or ISO/IEC 17025 frameworks, manual logbook entries—including operator ID, date/time stamp, and reference measurement values—must accompany all positional adjustments to maintain audit-ready traceability. Documentation templates for such records are available upon request from authorized distributors.

Applications

• Laser cavity alignment in diode-pumped solid-state (DPSS) and fiber laser systems
• Adjustment of etalon spacing in wavelength-stabilized laser sources
• Positioning of photodetectors or fiber collimators in free-space optical communication testbenches
• Calibration of spectrometer entrance slits and grating mounts
• Teaching laboratory experiments involving wavefront shearing, Michelson interferometry, and polarization state analysis
• Integration into custom-built optical coherence tomography (OCT) reference arms

FAQ

Is the HTAC-RC-03 compatible with Thorlabs or Newport mounting hardware?
Yes—the 8 mm dovetail groove conforms to the ANSI/ISO 10993-12 standard for optical rail interoperability and accepts standard M4 mounting screws used across major OEM platforms.

Can this stage be used in vacuum environments?
No—its PTFE coating and internal grease-free mechanism are rated only for ambient air operation (1 atm, 20–25°C); outgassing characteristics have not been tested per ASTM E595.

What is the maximum recommended load for maintaining specified repeatability?
2 N axial load (≈200 gf); exceeding this may induce elastic deformation in the micrometer shaft and degrade positional fidelity.

Does the stage include mounting hardware?
Standard delivery includes two M3 × 8 mm socket-head cap screws for base attachment; additional adapters (e.g., post holders, cage plate mounts) are sold separately.

Is technical documentation available in English?
Yes—dimensional drawings, material certifications, and assembly instructions are provided in English PDF format upon order confirmation.
