HTSL25-X Manual Translation Stage with 25 mm Travel and Left-Side Micrometer Drive

Overview

The HTSL25-X is a high-precision manual translation stage engineered for stable, repeatable linear displacement in optical alignment, interferometry, and laboratory-scale photonics setups. Designed according to ISO 10110–7 and DIN 3141 standards for optical mounting hardware, it employs a dual-rail linear ball bearing architecture to minimize yaw, pitch, and roll deviations across its full 25 mm travel range. The stage utilizes a calibrated micrometer head (0.5 mm pitch, 0.01 mm graduation) for fine positional control, delivering sub-micron repeatability under typical lab conditions (23 ± 2 °C, <50% RH). Its left-side drive configuration enables ergonomic access in constrained optical benches and facilitates integration into multi-axis kinematic stacks without obstructing central optical paths.

Key Features

• Precision linear motion via preloaded ball-bearing guide rails — optimized for low friction and minimal hysteresis
• Micrometer-driven actuation with tactile feedback and engraved scale for direct readout and consistent adjustment
• Left-side drive architecture — preserves central aperture clearance and simplifies co-alignment with beam paths
• Dual-spring anti-backlash mechanism — eliminates axial play and ensures consistent zero-reference stability over repeated cycles
• Standardized mounting interface — top and base plates feature dual-pattern tapped holes (M4 at 25 mm grid and M6 at 50 mm grid) compliant with Thorlabs, Newport, and Standa mechanical ecosystems
• Black anodized aluminum construction (6061-T6) — provides corrosion resistance, thermal stability (CTE ≈ 23.6 × 10⁻⁶ /°C), and non-magnetic compatibility for sensitive instrumentation environments

Sample Compatibility & Compliance

The HTSL25-X is compatible with standard optical components up to 100 mm × 100 mm footprint and 2 kg static load. It supports vacuum-compatible variants upon request (V-spec: dry-lubricated bearings, no adhesives, outgassing tested per ASTM E595). While not certified for cleanroom Class 100 operation, its surface finish (Ra ≤ 0.8 µm) and absence of particulate-generating materials meet ISO 14644–1 Class 5 baseline requirements for benchtop optical assembly. The stage conforms to RoHS 2015/863/EU and REACH SVHC screening protocols. No electrical or laser safety certification applies, as it is a passive mechanical positioning device.

Software & Data Management

As a purely manual stage, the HTSL25-X requires no firmware, drivers, or software integration. Positional data is recorded manually via micrometer scale reading or externally via compatible digital calipers (e.g., Mitutoyo IP67 series) interfaced through USB or RS-232 to LabVIEW, Python (PySerial), or MATLAB environments. For traceable metrology workflows, users may log adjustments in accordance with ISO/IEC 17025 documentation requirements — including operator ID, environmental conditions, and calibration certificate references for associated measurement tools.

Applications

• Alignment of collimated beams in Michelson and Mach–Zehnder interferometers
• Positioning of fiber couplers, photodetectors, or objective lenses in confocal microscopy breadboards
• Stepwise translation in optical coherence tomography (OCT) reference arms
• Integration into XYZ stack assemblies for spatial scanning of photonic integrated circuits (PICs)
• Calibration target movement in laser beam profiler validation procedures (per ISO 11146–2)
• Adjustment of grating angles in compact spectrometer prototypes

FAQ

Is the HTSL25-X compatible with motorized controller systems?
No — it is a fully manual stage. However, its standardized mounting pattern allows mechanical coupling to third-party stepper-motor actuators (e.g., Zaber T-NA series) using custom adapter plates.
What is the maximum recommended load for dynamic operation?
2 kg static; for repetitive motion at >1 Hz, reduce to 1.2 kg to maintain ≤ ±1.5 µm repeatability over 10⁴ cycles.
Can the micrometer head be replaced with a different pitch or scale?
Yes — the stage accepts industry-standard 8–32 UNC micrometer heads; replacement units must maintain axial runout < 5 µm to preserve specification compliance.
Does the stage include mounting screws or leveling feet?
No — fasteners are sold separately to ensure compatibility with user-specific substrate materials and torque specifications.
Is technical documentation available in English with dimensional drawings?
Yes — CAD models (STEP, IGES) and PDF dimensional drawings with GD&T annotations are provided upon request under NDA for integration verification.
