ASM75-XY Two-Axis Manual Translation Stage by ZOLIX

Overview

The ASM75-XY Two-Axis Manual Translation Stage is a precision-engineered mechanical positioning platform developed by ZOLIX (Beijing Zolix Instruments Co., Ltd.) for demanding optical alignment, laser beam steering, and micro-optical component adjustment applications. Built on a modular, rigid aluminum alloy frame, this stage implements orthogonal dual-axis translation via high-precision micrometer-driven lead screws and preloaded linear bearings—ensuring minimal wobble, repeatable sub-10 µm positioning accuracy, and long-term stability under static and low-dynamic loading conditions. Unlike motorized or piezoelectric alternatives, the ASM75-XY prioritizes mechanical simplicity, tactile control, and immunity to electromagnetic interference—making it especially suitable for ultra-low-noise interferometric setups, vacuum-compatible optical tables (with optional anodized or stainless-steel variants), and educational laboratory environments where intuitive manual adjustment remains essential. Its design adheres to standard optical rail mounting conventions (e.g., M4 and M6 threaded holes on base and top plates), facilitating seamless integration into existing ZOLIX and third-party optical benches.

Key Features

• Orthogonal XY motion architecture with independent, calibrated micrometer drives—each offering 75 mm total travel and 10 µm minimum incremental resolution
• Integrated TSM75D-1C linear stage pair, engineered for parallelism tolerance ≤15 arcsec over full stroke and bidirectional repeatability ≤±3 µm
• Two BP-28 universal adapter plates included—enabling standardized mounting of kinematic mirrors, lens holders, fiber couplers, or photodetectors with 25.4 mm or 50.8 mm clear apertures
• Black anodized aluminum construction (6061-T6) providing corrosion resistance, thermal stability (CTE ≈ 23.6 × 10⁻⁶ /°C), and non-magnetic performance
• No external power or controller required—ideal for use in RF-shielded rooms, cryogenic enclosures (with optional cold-stage variants), and Class 100 cleanroom-adjacent optical workstations

Sample Compatibility & Compliance

The ASM75-XY accommodates payloads up to 2.5 kg uniformly distributed across its 120 mm × 120 mm top plate. It supports standard optical components including Ø25.4 mm and Ø50.8 mm lens mounts, kinematic mirror mounts (KMM series), and fiber launch assemblies—all without compromising planarity or tip/tilt stability. While not certified for medical or aerospace-grade qualification, the stage complies with general laboratory equipment safety standards (IEC 61010-1:2010) and is manufactured under ISO 9001:2015 quality management systems. Its mechanical interface conforms to common OEM specifications referenced in ISO 10110-7 (optical element mounting) and ANSI/OEOSC OP1.002 (optomechanical interface dimensions). No hazardous substances are used per RoHS Directive 2011/65/EU.

Software & Data Management

As a purely manual mechanical stage, the ASM75-XY does not incorporate embedded electronics, sensors, or digital interfaces—and therefore requires no firmware, drivers, or proprietary software. Position data is recorded manually using engraved scale markings (0.1 mm graduations) and vernier-assisted micrometer dials. For labs implementing digital lab notebooks (e.g., LabArchives, Benchling) or LIMS-integrated workflows, users may log coordinates, timestamps, and experimental context via standard CSV or JSON export from external metrology tools (e.g., laser interferometers or coordinate measuring machines used for calibration verification). Audit trails remain traceable through documented calibration certificates (available upon request) aligned with GLP principles for non-regulated research environments.

Applications

• Precise alignment of collimated beams in Michelson or Mach–Zehnder interferometers
• Positioning of grating monochromators and spectrograph entrance slits in UV-Vis-NIR spectrometers
• Iterative optimization of coupling efficiency between single-mode fibers and photonic integrated circuits
• Stage-based scanning in confocal fluorescence microscopy prototypes (when paired with stepper-motor actuators externally)
• Teaching laboratories for demonstrating Cartesian coordinate manipulation, error propagation in multi-axis systems, and Abbe offset analysis

FAQ

Is the ASM75-XY compatible with vacuum environments?
Yes—standard units operate at ambient pressure; vacuum-compatible versions (with dry-lubricated leadscrews and vented housing) can be ordered separately.
Can I replace the micrometer knobs with motorized actuators?
The stage features 6 mm diameter leadscrew shafts with standard 0.75 mm pitch—compatible with many off-the-shelf stepper or servo couplers, though structural reinforcement may be required for dynamic loads.
What is the maximum allowable load at full 75 mm extension?
2.5 kg centered load maintains ≤5 µrad angular deviation; off-center loads exceeding 1.2 kg require torque compensation per ZOLIX Application Note AN-ASM75-01.
Are replacement BP-28 adapter plates available as spare parts?
Yes—BP-28 plates are catalogued under part number Z-BP28-AL and shipped with M3 × 0.5 mounting hardware.
Does ZOLIX provide calibration documentation?
A factory-verified positional accuracy report (per ISO 230-2 Annex B) is provided with each unit; NIST-traceable calibration services are available upon request.
