ASM25XY-RV Four-Axis Precision Translation and Rotation Stage

Overview

The ASM25XY-RV is a fully integrated four-axis precision positioning stage engineered for demanding optical alignment tasks in research laboratories and advanced photonics development environments. It combines orthogonal linear motion along the X and Y axes, vertical translation along the Z axis, and full 360° continuous rotation about the vertical (θz) axis—enabling precise spatial repositioning and angular orientation of optical components such as mirrors, lenses, fiber couplers, or detectors. The stage operates on a modular architecture, integrating three certified sub-stages: the TSM25-1A high-stability linear translation stage (X/Y), the RSM82-1A precision rotary stage with fine angular resolution and low wobble, and the TSMV5-1A compact vertical lift stage (Z). All mechanical interfaces comply with standard M4 and M6 mounting patterns, facilitating seamless integration into existing optical tables and breadboard systems. Its design adheres to fundamental principles of kinematic stability and minimal Abbe error—critical for applications requiring sub-microradian angular repeatability and micron-level positional fidelity.

Key Features

• Four-degree-of-freedom motion control: independent, decoupled adjustment of X, Y, Z, and θz axes
• High-resolution manual actuation via differential micrometer drives (10 µm per division on X/Y; 5 µm per division on Z; 0.05° per division on θz)
• Low-profile stacked configuration (< 95 mm total height) preserving optical path clearance
• Stainless steel construction with black anodized aluminum plates for thermal stability and corrosion resistance
• Pre-aligned mechanical coupling between modules ensures coaxiality and minimizes parasitic tilt during Z translation or θz rotation
• Integrated locking mechanism on all axes to maintain position under vibration or thermal drift

Sample Compatibility & Compliance

The ASM25XY-RV is compatible with standard Ø25.4 mm and Ø50.8 mm optical mounts, lens tubes, and kinematic mirror mounts. Its load capacity supports up to 2.5 kg uniformly distributed, making it suitable for medium-weight optics including beam splitters, objective lenses, and photodetector assemblies. The stage meets mechanical design requirements referenced in ISO 10110-7 (optical component mounting) and aligns with best practices outlined in ANSI/OPI RP-1 for optical positioning equipment. While not certified for cleanroom use by default, its non-outgassing materials and absence of lubricants in critical motion paths allow adaptation for Class 1000 cleanroom environments with optional vacuum-compatible variants available upon request.

Software & Data Management

Although the ASM25XY-RV is primarily a manually operated stage, it is fully compatible with third-party motorized upgrade kits—including stepper motor adapters for the TSM25-1A and RSM82-1A modules—and supports integration with common motion control platforms such as Thorlabs Kinesis, Newport APT, and LabVIEW-based DAQ systems. When equipped with encoders (optional), positional feedback enables closed-loop operation and traceable movement logging. All calibration data—including axis orthogonality correction matrices and backlash compensation profiles—can be stored in vendor-neutral XML format for auditability. The system supports GLP-compliant documentation workflows when used in regulated environments (e.g., metrology labs conducting ISO/IEC 17025-accredited measurements).

Applications

• Laser cavity alignment and mode-matching optimization in ultrafast and CW laser systems
• Fiber-to-waveguide coupling alignment in integrated photonics packaging
• Interferometric reference arm positioning in Michelson and Mach–Zehnder configurations
• Multi-angle reflectance and scattering characterization of microstructured surfaces
• Calibration target positioning in automated optical inspection (AOI) stations
• Alignment of multi-element objectives in confocal and STED microscopy test benches

FAQ

Is the ASM25XY-RV compatible with motorized controllers?
Yes—mechanical interface dimensions and mounting hole patterns conform to industry standards, enabling retrofitting with OEM or third-party stepper/servo actuators.
What is the typical angular repeatability of the RSM82-1A rotary module?
Under controlled lab conditions (23 ± 1°C, no external vibration), angular repeatability is ≤ ±15 arcseconds over repeated 360° rotations.
Can this stage be used in vacuum environments?
Standard units are not vacuum-rated; however, ZOLIX offers custom versions with vacuum-compatible greases, stainless steel fasteners, and vented base plates for pressures down to 10⁻⁶ Torr.
Does the assembly include alignment certification documentation?
Each shipped unit includes a factory alignment report listing measured orthogonality deviations (X/Y vs Z), runout of the θz axis (< 5 µm TIR), and Z-axis straightness (≤ 1.2 µm over 5 mm travel).
Are replacement parts available for individual sub-stages?
Yes—TSM25-1A, RSM82-1A, and TSMV5-1A are sold separately with full mechanical and dimensional interchangeability across ZOLIX’s product line.
