Overview
The Hanting HTRH-P Series Adjustable Optical Post Holder is a precision-engineered mechanical mounting solution designed for stable, repeatable height adjustment of optical components in laboratory and industrial optical setups. Based on the proven HTR-series support rod architecture, this post holder employs a robust clamping mechanism that secures metric or imperial stainless-steel posts (e.g., 1/4″-20, M6, M8) with high axial rigidity and minimal lateral drift. Its core function is to provide vertical positioning repeatability within ±5 µm over repeated tightening cycles—critical for alignment-sensitive applications such as laser cavity construction, interferometric beam paths, and multi-axis optomechanical assemblies. The device operates without active electronics or software; its performance relies entirely on mechanical design integrity, surface finish quality, and material stability under thermal and vibrational loads.
Key Features
- Height-adjustable platform with fine-threaded vertical translation (M4 or M6 internal thread depending on model), enabling precise Z-axis positioning across the full travel range (25 mm, 50 mm, 75 mm, or 100 mm per model)
- Bimodal compatibility: accepts both standard metric (e.g., M6 × 0.75, M8 × 1.0) and imperial (1/4″-20 UNC, 5/16″-18 UNC) stainless-steel posts without adapters
- Integrated neodymium-based magnetic base (NdFeB, N35 grade) offering >12 N holding force on ferromagnetic surfaces; base includes non-magnetic stainless steel shielding to minimize stray field emission
- Locking lever mechanism with dual-point contact geometry ensures uniform clamping pressure and eliminates post slippage under static loads up to 15 kg
- CNC-machined 6061-T6 aluminum body with hard-anodized (Type II, 25 µm thickness) surface finish for corrosion resistance and dimensional stability
- Zero-play set-screw interface for secondary rotational locking when used with rotationally indexed posts
Sample Compatibility & Compliance
The HTRH-P series is compatible with industry-standard optical posts from Thorlabs, Newport, and Standa, including Ø6 mm, Ø12.7 mm, and Ø25.4 mm diameters. It supports ISO 9001-certified manufacturing processes and conforms to RoHS 2011/65/EU directive requirements for hazardous substance restriction. While not certified to ISO/IEC 17025 as a measurement instrument, its mechanical tolerances align with common optical alignment practices defined in ISO 10110-7 (surface form tolerances) and ANSI/OEOSC OP1.002 (optomechanical interface standards). Magnetic base usage complies with IEC 62366-1 usability engineering guidelines for lab equipment—users are advised to maintain ≥20 cm clearance from pacemakers, mechanical watches, and magnetic storage media during installation.
Software & Data Management
This is a purely mechanical component with no embedded firmware, connectivity interfaces, or data logging capability. Integration into automated systems requires external motion controllers (e.g., Newport ESP300, Thorlabs KDC101) paired with compatible motorized posts. For documentation traceability in GLP/GMP environments, each unit carries a permanent laser-engraved serial number and batch code, supporting audit-ready inventory tracking. CAD models (STEP, IGES, SolidWorks) and dimensional drawings are available upon request for integration into optical layout simulations (Zemax OpticStudio, FRED, CODE V).
Applications
- Laser diode and fiber-coupled source alignment in Raman spectroscopy and OCT systems
- Vertical positioning of mirrors, beamsplitters, and waveplates in Michelson and Mach-Zehnder interferometers
- Mounting and leveling of CCD/CMOS imaging sensors in spectral calibration rigs
- Adjustable-height support for collimators and objective lenses in confocal microscopy staging
- Modular integration into custom-built optical tables where thermal expansion compensation is required via differential material selection
FAQ
What is the maximum recommended load capacity for the HTRH75P model?
The static vertical load limit is 15 kg at room temperature (23 ± 2 °C); dynamic loads exceeding 5 Hz vibration frequency require additional damping evaluation.
Can the magnetic base be disabled or shielded for use near sensitive instruments?
Yes—the base incorporates a removable 1.2 mm-thick mu-metal shim (included) that reduces residual field strength by >90% at 10 mm standoff distance.
Are replacement clamping screws and base magnets available as spare parts?
Yes—standard M4 × 0.7 pitch socket head cap screws and N35-grade magnet modules (part numbers HT-MAG-N35-12x3mm) are stocked and shipped globally.
Does this post holder meet vacuum compatibility requirements for UHV applications?
No—it is rated for ambient air use only; outgassing characteristics have not been tested per ASTM E595, and anodized aluminum surfaces are not UHV-compatible.
Is there a version with metric-only threading and no magnetic base?
Yes—the HTRH-P-NM variant (non-magnetic) is available with M6 × 1.0 internal thread and 304 stainless steel base; lead time is 4–6 weeks.
