Park Accurion Nano Series Active Vibration Isolation Table

Overview

The Park Accurion Nano Series Active Vibration Isolation Table is an engineered solution for laboratories requiring precise mechanical stability in the sub-hertz to kilohertz frequency range. Based on real-time inertial sensing and electromagnetic actuation, the system implements closed-loop, six-degree-of-freedom (6-DOF) active vibration cancellation—simultaneously suppressing translational (X, Y, Z) and rotational (pitch, yaw, roll) disturbances. Unlike passive damping systems constrained by resonance limitations, the Nano Series initiates active compensation at 0.7 Hz and maintains >30 dB attenuation across 0.7–100 Hz, bridging the critical low-frequency gap where floor-borne seismic noise, building sway, and HVAC-induced vibrations dominate. Its design targets applications where thermal drift, electromagnetic interference (EMI), or mechanical coupling would compromise measurement fidelity—particularly atomic force microscopy (AFM), scanning probe microscopy (SPM), laser Doppler vibrometry, and nanomechanical testing platforms operating inside acoustic enclosures or laminar flow hoods.

Key Features

• True 6-DOF active isolation with no manual tuning: Eliminates need for load calibration, leveling screws, or pneumatic pressure adjustment.
• Sub-second system readiness: Achieves full operational stability within 0.3 seconds after power-on—no warm-up or settling delay.
• Thermally neutral operation: External controller housing isolates heat-generating electronics from the isolation surface, maintaining thermal homogeneity essential for interferometric and cryogenic setups.
• EMI-resilient architecture: Controller located remotely via shielded data cable; zero onboard switching regulators or high-frequency clock sources near sensitive instrumentation.
• Robust mechanical foundation: Optional welded steel support tables provide high static and dynamic stiffness (≥10⁶ N/m vertical, ≥5×10⁵ N/m horizontal), minimizing modal coupling between table and instrument.
• Compact footprint and lightweight integration: Bench-top form factor (standard platform sizes: 600 × 600 mm and 800 × 800 mm) compatible with standard fume hoods, gloveboxes, and ISO Class 5 cleanroom configurations.

Sample Compatibility & Compliance

The Nano Series is validated for use with instruments having mass ranges from 5 kg to 80 kg and center-of-gravity height ≤ 150 mm above the isolation surface. It complies with ISO 20486:2018 (Vibration isolation—Active systems—Performance evaluation methods) and supports audit-ready documentation per GLP and GMP requirements. The absence of compressed air or hydraulic components simplifies facility integration and eliminates contamination risks associated with oil-lubricated actuators or air-line particulates. All electrical interfaces meet IEC 61000-6-3 (EMC emission limits) and IEC 61000-6-2 (immunity standards). For regulated environments, optional firmware logging enables timestamped event tracking aligned with FDA 21 CFR Part 11 data integrity principles.

Software & Data Management

The Nano Series operates autonomously without host PC dependency—controller firmware handles real-time feedback loop execution at 10 kHz sampling rate. Optional USB/RS-485 interface enables integration with LabVIEW, MATLAB, or Python-based monitoring scripts for performance trending, disturbance spectrum analysis, and alarm-triggered logging. Built-in diagnostic mode provides FFT-based vibration spectral snapshots (0.1–200 Hz resolution bandwidth), allowing users to quantify residual motion amplitude before and after installation. Audit trails—including power cycles, configuration changes, and fault events—are stored in non-volatile memory with UTC timestamps and user-accessible export (CSV format).

Applications

• Atomic force microscopy (AFM) and scanning tunneling microscopy (STM) requiring sub-nanometer positional stability.
• Optical coherence tomography (OCT) and digital holographic microscopy where phase noise directly impacts axial resolution.
• Nanoindentation and microhardness testers where low-frequency oscillations distort load-displacement curves.
• Single-molecule fluorescence imaging systems (e.g., TIRF, STORM) sensitive to stage drift during long-exposure acquisition.
• Quantum sensing platforms (NV-center magnetometers, cold-atom interferometers) demanding ultra-low mechanical noise floors.
• Calibration labs performing ISO/IEC 17025-compliant dimensional metrology on coordinate measuring machines (CMMs) or laser trackers.

FAQ

Does the Nano Series require periodic recalibration or maintenance?
No. The system employs factory-trimmed MEMS accelerometers and self-compensating electromagnetic actuators. No field recalibration is specified under normal operating conditions per ISO 14644-1 environmental classifications.
Can it be used in vacuum or controlled atmosphere chambers?
The isolation platform itself is compatible with ambient-pressure inert gas environments. For vacuum integration, the external controller must remain outside the chamber; feedthrough-rated signal cables are available upon request.
Is the system compatible with existing laboratory power infrastructure?
Yes. It operates from standard 100–240 VAC, 50/60 Hz single-phase supply with ≤150 W peak draw—no dedicated circuits or UPS required for basic operation.
How is performance verified post-installation?
Accurion provides a certified test report with each unit, including broadband transmissibility curves (0.1–200 Hz) measured per ISO 20486 Annex B using reference seismometers. Field verification kits (accelerometer + DAQ) are available as accessories.
What mounting options exist for integrating large or asymmetric instruments?
Custom-machined adapter plates and kinematic mounts are supported through Accurion’s engineering services team. All standard platforms feature M6 threaded inserts on 25-mm grid spacing for flexible fixture attachment.
