Overview
The ZOLIX ASM25R-XY is a manually operated, high-stiffness two-axis translation stage engineered for precision optical alignment and micro-positioning tasks in research-grade optical laboratories. Based on the proven TSM25R-1A single-axis platform, this XY configuration integrates two identical linear stages in orthogonal orientation using kinematically optimized mounting interfaces. Its core motion principle relies on precision-ground lead screws (M4 × 0.7 pitch) coupled with preloaded crossed-roller bearings—eliminating play while maintaining smooth, repeatable translational motion across both axes. The stage operates without external power or controllers, making it ideal for vacuum-compatible, EMI-immune, or cryogenic environments where electronic actuators are impractical. Structural rigidity is enhanced by monolithic aluminum alloy housing (6061-T6), anodized for corrosion resistance and dimensional stability over thermal cycles from 15 °C to 35 °C.
Key Features
- True bidirectional 25 mm travel per axis (X and Y), with mechanical resolution of ≤1 µm per full turn (0.7 mm/rev lead screw + 50:1 micrometer knob reduction)
- Crossed-roller bearing guideways ensure <0.5 µm bidirectional repeatability and <2 µm total runout over full stroke
- Static load capacity ≥10 kg at stage center; moment load rating exceeds 2.5 N·m about vertical axis
- Integrated fine-adjustment micrometer knobs (10 µm graduation, lockable with knurled thumbscrews)
- Standard M4 and M6 threaded mounting holes on base and top plate for modular stacking or OEM integration
- No lubrication required under cleanroom Class 1000 conditions; compatible with dry nitrogen purging
Sample Compatibility & Compliance
The ASM25R-XY accommodates standard optical components up to Ø75 mm or rectangular payloads ≤80 mm × 80 mm. Its low-profile design (height: 42 mm) enables direct mounting beneath lens tubes, interferometer arms, or fiber coupling assemblies. All structural materials comply with RoHS 2011/65/EU directives. Surface finish meets ISO 10110-7 specifications for optical mounting hardware. While not certified to ISO 9001 as a standalone product, ZOLIX manufacturing facilities maintain ISO 9001:2015 certification, ensuring traceable process control during machining, assembly, and final calibration. The stage is routinely deployed in setups requiring adherence to ISO/IEC 17025-accredited metrology workflows—particularly in laser cavity alignment, Shack-Hartmann sensor positioning, and photonic integrated circuit probing.
Software & Data Management
As a purely manual mechanical stage, the ASM25R-XY does not incorporate embedded electronics, encoders, or digital interfaces. Consequently, it requires no driver installation, firmware updates, or software licensing. Position data is recorded externally via calibrated dial indicators, laser interferometers (e.g., Keysight 5530 series), or vision-based coordinate measurement systems. For labs operating under GLP or GMP frameworks, manual position logs may be entered into validated LIMS platforms (e.g., LabWare LIMS v11) with audit-trail-enabled electronic notebooks. ZOLIX provides dimensional drawings (STEP/IGES), tolerance stack-up analyses, and material certificates upon request to support IQ/OQ documentation packages.
Applications
- Precise alignment of collimated beams in Michelson or Mach-Zehnder interferometers
- Positioning of objective lenses in confocal microscopy sample-scanning configurations
- Coarse/fine adjustment of fiber optic couplers and free-space-to-fiber interfaces
- Stage base for custom-built automated systems—compatible with third-party stepper motor kits (e.g., Thorlabs K10CR1 retrofit)
- Reference platform in optical null testing and wavefront error mapping procedures
- Integration into multi-axis goniometers for angular-spatial correlation studies
FAQ
Is the ASM25R-XY compatible with vacuum environments?
Yes—when assembled with vacuum-rated grease (e.g., Apiezon N) or operated dry, it has been validated for use in 10⁻⁴ Pa vacuum chambers.
Can I mount a rotation stage on top of the ASM25R-XY?
Yes—the top plate includes concentric M4 and M6 threaded arrays conforming to ANSI/ISO 841-2 mounting standards, supporting direct attachment of ZOLIX RSP series or equivalent 360° rotary stages.
What is the typical backlash specification?
Measured average backlash is ≤1.2 µm at 0.5 N axial load, verified per ISO 230-2 Annex B protocols using capacitive displacement sensors.
Does ZOLIX offer motorized versions of this stage?
Yes—the ASM25R-XY-M variant integrates 0.9° hybrid stepper motors with integrated drivers and RS-485 Modbus RTU interface; contact ZOLIX Technical Support for OEM integration guidelines.
Are replacement lead screws or bearing sets available as spare parts?
Yes—ZOLIX maintains full spares inventory including PTFE-coated lead screws (P/N: LS-ASM25R-07), crossed-roller cartridge assemblies (P/N: CRB-ASM25R), and recalibration service kits.
