HanDing HTVS25/50 Manual Vertical Translation Stage

Overview

The HanDing HTVS25/50 Manual Vertical Translation Stage is an engineered solution for precise, repeatable vertical positioning in optical alignment and experimental setups. Based on a robust micrometer-driven linear motion architecture, it employs a high-efficiency lead screw mechanism with backlash-compensated nut engagement to ensure smooth, low-hysteresis vertical displacement. Unlike motorized alternatives, this stage prioritizes mechanical stability, zero electromagnetic interference, and long-term dimensional integrity—critical attributes for interferometric systems, laser cavity alignment, and vibration-sensitive optical benches. Its rigid anodized aluminum base and integrated locking clamp minimize parasitic tilt or drift during static operation, making it suitable for applications requiring sub-10 µm repeatability over extended thermal cycles.

Key Features

• Two standard travel options: 25 mm and 50 mm, selected at time of order to match optical path constraints and payload height requirements.
• Micrometer head with 0.01 mm graduation and vernier scale for manual resolution down to ±5 µm typical positioning uncertainty.
• Integrated mechanical lock lever that secures the platform without introducing lateral shift or angular deviation.
• Top plate features multiple M4 and M6 threaded mounting holes (standard ISO metric pattern) compatible with common optical posts, kinematic mounts, and lens holders.
• Low-profile design (height < 65 mm for HTVS25 variant) enables integration beneath breadboards or within compact optical enclosures.
• Surface finish and dimensional tolerances conform to ISO 2768-mK general tolerancing standards for laboratory-grade mechanical components.

Sample Compatibility & Compliance

The HTVS25/50 accommodates diverse optical payloads including collimators, fiber launch assemblies, detector modules, and small interferometer heads. Its flat, ground stainless steel top surface ensures minimal wavefront distortion when used under collimated beams. The stage meets CE marking requirements for electrical safety and mechanical hazard compliance (EN ISO 12100). While not certified to GLP/GMP validation protocols per se, its deterministic mechanical behavior, absence of firmware or software dependencies, and traceable manufacturing origin support qualification under internal lab SOPs for regulated environments (e.g., ISO/IEC 17025-accredited calibration labs). It is routinely deployed in university teaching labs (per ANSI Z359.1-aligned safety practices) and industrial R&D settings where auditability of mechanical positioning history is maintained via logbook documentation.

Software & Data Management

This is a purely manual mechanical stage with no embedded electronics, firmware, or digital interface. Consequently, it requires no driver installation, firmware updates, or cybersecurity configuration. Position data is recorded manually—either via direct micrometer reading or through external metrology tools such as dial indicators, capacitive sensors, or laser displacement interferometers (e.g., Keysight 5530 series). For laboratories operating under FDA 21 CFR Part 11 or EU Annex 11 guidelines, position logs generated using validated external measurement devices may be incorporated into electronic lab notebooks (ELN) with full audit trail capability. No proprietary software is associated with the stage; all operational documentation—including dimensional drawings, torque specifications for mounting screws, and thermal expansion coefficients—is provided in English PDF format upon request.

Applications

• Laser beam height adjustment in multi-axis optical tables, especially for coupling into single-mode fibers or waveguides.
• Vertical fine-tuning of objective lenses in custom-built microscopy rigs where motorized Z-stages introduce vibration or EMI.
• Alignment of retroreflectors and corner cubes in Michelson or Mach–Zehnder interferometers.
• Height calibration reference for profilometers and white-light interferometers during system verification.
• Stable elevation platform for photodetectors in quantum optics experiments involving photon counting under cryogenic or vacuum-compatible adaptations (when paired with optional vacuum-flange adapters).
• Teaching tool in undergraduate optics laboratories for demonstrating mechanical resolution limits, hysteresis, and thermal drift in precision translation systems.

FAQ

Is the HTVS25/50 compatible with Thorlabs or Newport optical posts?

Yes—the top plate includes standardized M4 and M6 tapped holes on 25 mm and 50 mm pitch grids, fully interoperable with industry-standard post holders from Thorlabs (e.g., PH3, PH6), Newport (e.g., KM100, UH1), and similar manufacturers.

Can this stage be mounted upside-down or in horizontal orientation?

It is mechanically rated for vertical (Z-axis) use only. Horizontal mounting compromises load-bearing integrity and voids the manufacturer’s specification for maximum payload capacity.

What is the recommended torque for mounting screws?

M4 screws: 0.7 N·m maximum; M6 screws: 1.8 N·m maximum. Over-torquing may deform the aluminum base or strip threads.

Does HanDing provide calibration certificates?

Factory calibration is not included by default, but third-party accredited metrology labs can perform traceable vertical displacement verification per ISO/IEC 17025 using laser interferometry or coordinate measuring machines (CMM).

Is there a vacuum-compatible version available?

Standard units are not vacuum-rated; however, custom variants with vacuum-compatible greases, stainless steel fasteners, and outgassing-tested anodization are available upon engineering consultation and minimum order quantity agreement.
