Overview
The HTMR13-NS is a high-precision manual translation stage engineered for stable, repeatable linear displacement in optical alignment, interferometry, and micro-positioning applications. Designed around a robust linear ball bearing rail system, it delivers smooth, low-friction motion with minimal wobble and angular deviation—critical for beam path stability in laser cavity alignment, fiber coupling, and confocal microscopy setups. Its 13 mm unidirectional travel range is actuated via a right-side mounted micrometer head, enabling ergonomic operation without obstructing optical access to the stage top or adjacent components. The stage employs a spring-loaded preload mechanism to eliminate axial backlash, ensuring consistent positional reproducibility (< ±1 µm) across repeated cycles—a prerequisite for quantitative optical metrology and calibration workflows.
Key Features
- Precision linear ball bearing guideway ensures sub-micron straightness and angular stability over full travel
- Right-side micrometer drive configuration preserves central optical access and simplifies integration into multi-axis kinematic mounts
- Integrated anti-backlash spring preload eliminates play in the lead screw interface, enhancing positioning fidelity
- Modular actuation compatibility: accepts standard 0.5 mm pitch micrometer heads, differential micrometers (10:1 or 25:1 ratio), or custom fine-pitch screws (e.g., 0.25 mm/rev)
- Top plate features a standardized 25 mm pitch grid of M4 tapped holes, conforming to ISO 8015 and common optomechanical mounting conventions
- Anodized 6061-T6 aluminum base provides dimensional stability, thermal uniformity, and corrosion resistance in ambient laboratory environments
- Stainless steel critical wear surfaces—including lead screw, nut, and rail contact zones—ensure long-term mechanical integrity
Sample Compatibility & Compliance
The HTMR13-NS is designed for use with passive optical components (lenses, mirrors, filters, waveplates), fiber optic collimators, detector mounts, and sensor carriers. It does not incorporate active sensing or environmental control; therefore, no regulatory certification (e.g., CE, RoHS) applies to its mechanical function. However, its construction materials and surface finish comply with ISO 10110-7 (optical component cleanliness) and SEMI F21 (cleanroom-compatible material outgassing limits) when used in controlled environments. The stage meets general laboratory safety requirements per ANSI Z535.4 for mechanical labeling and force-limited manual operation. No hazardous substances are employed in structural fabrication, and all metallic components are non-magnetic (relative permeability μr ≈ 1.00002), suitable for MRI-adjacent or electron-optical systems.
Software & Data Management
As a purely manual mechanical stage, the HTMR13-NS requires no firmware, drivers, or software integration. Position readout is performed visually via the micrometer scale (typically graduated in 1 µm increments, with vernier estimation to 0.5 µm). For traceable calibration, users may pair the stage with external metrology tools such as laser interferometers (e.g., Keysight 5530 series), capacitive sensors (Micro-Epsilon capaNCDT), or digital dial indicators (Mitutoyo Absolute Series). Documentation includes dimensional drawings (ISO 1101 geometric tolerancing), material certificates (ASTM B209 for aluminum alloy), and assembly instructions compliant with ISO 9001:2015 production controls.
Applications
- Laser beam steering and cavity length tuning in CW and pulsed solid-state laser systems
- Fiber-to-fiber or fiber-to-waveguide coupling alignment in photonic integrated circuit testing
- Stage-based scanning in white-light interferometry and optical coherence tomography (OCT) reference arms
- Position calibration of CCD/CMOS sensors in spectral imaging and radiometric setup verification
- Integration into XYZ stack configurations using compatible dovetail or kinematic base plates
- Education and training platforms for teaching precision mechanics, error budgeting, and uncertainty propagation in optical engineering labs
FAQ
Is the HTMR13-NS compatible with Thorlabs or Newport mounting rails?
Yes—the M4 hole pattern and 25 mm grid spacing align with industry-standard optomechanical mounting conventions used by Thorlabs, Newport, and Standa.
Can the micrometer head be replaced with a motorized actuator?
The stage does not include motorization provisions, but the micrometer mounting thread (M12×0.5) can be adapted using third-party couplers for stepper or piezo-driven conversion—subject to user-modification and load/torque validation.
What is the maximum recommended load for vertical orientation?
When mounted vertically, static load capacity is reduced to 2.5 kg to maintain guide rail lifetime and positional repeatability; dynamic loads must remain below 1.2 kg.
Does the stage include calibration documentation?
A factory-assembled unit includes a dimensional compliance report referencing ISO 2768-mK general tolerances and a visual inspection record; NIST-traceable calibration is available as an optional service.
Are replacement micrometer heads available from the manufacturer?
Standard metric micrometer heads (0–13 mm range, 0.5 mm pitch, 1 µm graduation) are commercially available; HT recommends part number MH-13S-R for optimal fit and torque consistency.
