Overview
The Accurion Sandwich1000-6.0 is a high-performance active vibration isolation platform engineered specifically for ultra-sensitive optical and nanoscale measurement systems operating in non-ideal laboratory environments. Unlike passive isolation solutions—such as air tables or elastomeric mounts—the Sandwich1000-6.0 employs real-time, closed-loop active control based on piezoelectric force actuation and inertial sensing. It continuously monitors ground-borne and structure-borne vibrations across six degrees of freedom (6-DOF), generating counteracting forces with sub-millisecond latency to suppress disturbances below 1 Hz—a critical capability for atomic force microscopy (AFM), scanning tunneling microscopy (STM), and high-magnification electron beam instrumentation. Its design eliminates inherent mechanical resonance modes typical of passive systems, thereby delivering broadband attenuation from sub-hertz up to several hundred hertz without performance trade-offs at low frequencies.
Key Features
- Active 6-DOF motion compensation using integrated piezoelectric actuators and high-sensitivity accelerometers
- No intrinsic mechanical resonance—enables stable operation under ambient floor vibrations as low as 0.1 Hz
- Standard 1000 mm × 1000 mm rigid granite-compatible top plate with precision-machined mounting interface (M6 threaded holes on 25 mm grid)
- Rated payload capacity of 6.0 kg, optimized for compact high-resolution instruments including AFM heads, optical interferometers, and micro-hardness testers
- Plug-and-play integration with standard AC mains power (100–240 VAC, 50/60 Hz); no external DC power supply or custom cabling required
- Modular architecture supporting optional upgrade paths—including Ethernet-based remote monitoring, analog I/O for external trigger synchronization, and firmware-upgradable control algorithms
Sample Compatibility & Compliance
The Sandwich1000-6.0 is validated for use with vibration-critical instruments requiring ISO 25317-compliant stability thresholds, including but not limited to: scanning probe microscopes (AFM/STM/UHV-STM), field-emission SEMs, confocal laser scanning microscopes, optical profilometers, patch-clamp electrophysiology rigs, and ultra-microbalances. Its performance aligns with the mechanical stability prerequisites defined in ASTM E2587 (Standard Practice for Scanning Electron Microscopy), ISO/IEC 17025 (for accredited calibration labs), and EU GMP Annex 11 (for regulated life science screening stations). The platform’s electromagnetic compatibility (EMC) meets EN 61326-1:2013 Class B requirements, ensuring co-location with sensitive RF and low-noise electronic subsystems without signal coupling.
Software & Data Management
The platform operates via an embedded ARM-based controller running deterministic real-time firmware. Configuration and diagnostics are accessible through a web-based GUI (HTTPS-secured, no local software installation required), supporting both IPv4 and IPv6 networks. System logs—including sensor raw data, actuator output history, and RMS displacement metrics—are timestamped and exportable in CSV format for traceability. Audit trails comply with FDA 21 CFR Part 11 requirements when deployed in regulated environments; user access levels (Operator, Engineer, Administrator) support role-based permissions. Optional API integration (RESTful endpoints over TLS) enables automated status polling and event-driven alerts within LIMS or MES infrastructure.
Applications
- Atomic Force Microscopy (AFM): Enables sub-angstrom Z-axis resolution by suppressing thermal drift and floor-induced lateral jitter
- UHV-STM Systems: Maintains tip-sample gap stability during long-duration tunneling current acquisition
- Optical Interferometry: Reduces phase noise in white-light or laser-based surface topography measurements
- Life Science Screening Stations: Stabilizes high-throughput imaging platforms used in phenotypic drug discovery assays
- Semiconductor Metrology Tools: Supports nanoscale CD-SEM alignment and overlay metrology repeatability
- Micro-Hardness Testing: Ensures consistent indenter contact force and dwell time fidelity under variable lab conditions
FAQ
What is the maximum supported payload for the Sandwich1000-6.0?
The platform is rated for a static load of 6.0 kg with center-of-gravity deviation ≤ ±15 mm from the geometric center.
Does it require compressed air or external cooling?
No—unlike pneumatic isolators, this system uses solid-state actuation and requires only standard AC power and ambient convection cooling.
Can it be integrated into existing optical tables or breadboards?
Yes—its bottom interface features countersunk M8 mounting holes compatible with standard optical table T-slots (e.g., Thorlabs, Newport), and the top plate accepts standard M6 fasteners.
Is remote monitoring available out of the box?
Yes—the built-in Ethernet port provides full web-based diagnostics, real-time vibration spectrum visualization, and configurable email/SNMP alerts.
How does it compare to passive damping in cleanroom environments?
Passive systems exhibit resonant amplification near their natural frequency (~2–4 Hz for air tables); the Sandwich1000-6.0 eliminates this limitation entirely, offering flat attenuation down to 0.1 Hz—critical for ISO Class 5+ cleanrooms where HVAC-induced pulsations dominate low-frequency noise.
