Abner AB-120XY Electric Dual-Axis Precision Translation Stage

Overview

The Abner AB-120XY Electric Dual-Axis Precision Translation Stage is a high-stiffness, low-drift motion platform engineered for sub-micron repeatability in optical alignment, semiconductor prototyping, and microfabrication workflows. Designed around a rigid aluminum base with precision-machined dovetail interfaces, the stage implements a dual-axis orthogonal translation architecture—X and Y axes driven by lead-screw–coupled stepper motors—to deliver deterministic displacement under open-loop or optional closed-loop control. Its operational principle relies on high-efficiency mechanical transmission (ball screw + crossed roller guide) rather than piezoelectric or voice-coil actuation, making it suitable for applications requiring sustained positional stability over extended duty cycles, moderate speed (≤15 mm/s), and robust resistance to thermal drift and mechanical vibration. The 120 × 120 mm anodized platform provides standardized M6 and 1/4″-20 threaded mounting patterns compatible with industry-standard optical posts, kinematic mounts, and vacuum chucks—enabling direct integration into upright microscopes, laser interferometry setups, or automated wafer probing stations.

Key Features

• 50 mm travel per axis (X/Y) with ≤ ±2 µm repeatability—validated per ISO 230-2 Annex B using laser interferometric measurement
• MISUMI-sourced precision ball screws (C5 grade) and preloaded crossed roller linear guides ensure minimal hysteresis and backlash (< 1.5 µm)
• Shinano Kenshi hybrid stepper motors provide high holding torque (0.25 N·m) and smooth microstepping resolution (1/16 step default, up to 1/256 via external driver)
• Black anodized 6061-T6 aluminum construction offers dimensional stability (CTE ≈ 23.6 ppm/°C), ESD-safe surface finish, and corrosion resistance
• Modular design supports optional Z-axis add-ons, manual θ rotation kits, or vacuum-compatible versions (V-series) with integrated 10⁻³ mbar-rated sealing
• Standard 0–5 V analog input and RS-485 interface enable synchronization with motion controllers (e.g., Thorlabs KDC101, Newport ESP301) or custom LabVIEW/Python automation scripts

Sample Compatibility & Compliance

The AB-120XY accommodates substrates ranging from 10 × 10 mm wafers to full 150 mm (6-inch) round samples when used with optional vacuum chucks or kinematic clamps. Its flatness tolerance of ≤3 µm over the full platform area meets ASTM E1317 requirements for optical bench-mounted instrumentation. While not certified for cleanroom Class 100 operation out-of-box, the stage complies with ISO 14644-1 particulate emission limits when operated at <30 rpm and equipped with non-shedding polymer covers. All electrical components meet IEC 61000-6-2 immunity standards for electrostatic discharge (±8 kV contact), radiated RF fields (10 V/m, 80 MHz–2 GHz), and fast transient bursts (±2 kV). Firmware-level position logging satisfies GLP audit trail requirements when paired with compliant host software.

Software & Data Management

Abner provides native support for Windows-based motion control via USB-to-RS485 bridge and ASCII command protocol (e.g., “MO”, “PA”, “PR”). Third-party compatibility includes MATLAB Instrument Control Toolbox, Python’s pySerial + numpy stack, and National Instruments DAQmx drivers. Position data can be timestamped and exported as CSV with millisecond resolution. Optional firmware upgrade enables non-volatile memory storage of up to 16 user-defined coordinate presets—useful for multi-step alignment routines in photolithography mask alignment or fiber coupling experiments. No cloud connectivity or proprietary runtime dependencies are required; all configuration remains local and deterministic.

Applications

• Semiconductor R&D: Wafer-level probe station positioning, mask-to-wafer alignment verification, and post-etch inspection stage calibration
• Optical assembly: Active alignment of laser diodes to fiber arrays, collimator tuning, and free-space interferometer cavity optimization
• 2D materials research: Precise registration of graphene/hBN heterostructures during dry-transfer processes using real-time optical feedback
• Microscopy enhancement: Integration beneath inverted microscopes for automated mosaic imaging, focus stacking, or correlative SEM-optical navigation
• Educational labs: Hands-on demonstration of coordinate transformation, PID control theory, and metrology traceability in undergraduate physics and mechatronics curricula

FAQ

Is the AB-120XY compatible with vacuum environments?
Standard units operate at ambient pressure only. Vacuum-rated variants (AB-120XY-V) feature sealed motor housings, vacuum-compatible lubricants, and flange-mounted feedthroughs—rated for 10⁻³ mbar continuous operation.
Can I achieve sub-micron positioning accuracy with open-loop control?
Repeatability is ≤ ±2 µm per axis under standard conditions. For true sub-micron absolute accuracy, optional encoder feedback (1 µm resolution quadrature output) and system-level calibration using interferometric reference are recommended.
What is the maximum payload capacity?
Static load rating is 5 kg centered; dynamic load limit is 2.5 kg at 10 mm/s. Exceeding these thresholds degrades repeatability and accelerates guide wear.
Does Abner supply controller hardware?
Yes—optional matched controllers include the AB-MC4 (quad-axis, RS-485, 12–24 VDC input) and AB-USB4 (USB-powered, four-channel microstepping driver with onboard current regulation).
Are CAD models and mounting templates available?
STEP and IGES files, along with 2D DXF mounting plate layouts, are provided free of charge upon request via Abner’s technical support portal.
