Overview
The DAEIL DVIO-R Series Damped Vibration Isolation Optical Table is an engineered solution for high-stability optical and precision metrology applications requiring passive vibration attenuation in laboratory, cleanroom, and R&D environments. Designed and manufactured by DAEIL Co., Ltd. (South Korea), the platform employs a proven three-layer sandwich architecture—comprising a top plate, steel honeycomb core, and structural baseplate—to deliver exceptional dynamic stiffness and broadband mechanical isolation. Its fundamental operating principle relies on mass-spring-damping behavior inherent to constrained-layer composite construction: the high-density 430-series ferromagnetic stainless steel top surface provides thermal stability and magnetic compatibility; the precision-welded steel honeycomb core (0.25 mm wall thickness, 3.2 cm² cell area) maximizes rigidity-to-weight ratio while suppressing resonant modes; and the integrated viscoelastic damping layer within the perimeter sidewalls—composed of high-loss polyethylene—dissipates energy across a wide frequency range (typically 1–100 Hz), effectively attenuating floor-borne and airborne vibrations. This architecture meets the foundational mechanical requirements for interferometry, laser alignment, nano-positioning, and quantum optics experiments where sub-micron stability is critical.
Key Features
- Three-layer monolithic sandwich construction: 4.0 mm thick 430-series high-permeability stainless steel top plate, laser-welded steel honeycomb core, and 4.0 mm carbon steel baseplate with oxide finish
- Perimeter sidewalls fabricated from 2.0 mm carbon steel encapsulating high-damping polyethylene, providing broadband energy dissipation without external active components
- Standard 25 mm × 25 mm grid of M6 threaded mounting holes, with each hole recessed into an individual cylindrical isolation cup for contamination control and simplified cleaning—critical for ISO Class 5–7 cleanroom compliance
- Flatness tolerance of ±0.1 mm over any 600 mm × 600 mm region, verified per ISO 10360-2 and traceable to NIST-traceable interferometric calibration protocols
- Modular height-adjustable support system with locking casters, enabling rapid reconfiguration and leveling across uneven laboratory floors
- Available standard table thicknesses: 50 mm, 100 mm, 200 mm, and 300 mm—selected based on required modal frequency separation and payload distribution profiles
Sample Compatibility & Compliance
The DVIO-R platform is compatible with standard optical components including kinematic mounts, translation stages, mirror holders, and fiber alignment fixtures conforming to ISO 10933 and DIN 8572 mechanical interface standards. Its non-magnetic top surface (430 stainless) ensures minimal perturbation in magnetic-sensitive setups such as electron beam lithography or magneto-optical trap (MOT) configurations. Surface oxidation and sealed isolation cups meet ASTM E2272-22 requirements for low-particulate emission in controlled environments. While the platform itself is not certified to ISO 14644-1, its design supports integration into ISO Class 5–7 cleanrooms when paired with appropriate air handling and static-dissipative flooring systems. The structural integrity complies with IEC 61000-4-28 (vibration immunity) and EN 60068-2-64 (broadband random vibration testing).
Software & Data Management
As a passive mechanical system, the DVIO-R requires no embedded firmware, drivers, or software. All dimensional specifications—including flatness maps, modal analysis reports, and load-deflection curves—are provided in PDF and CSV formats upon request, fully compatible with MATLAB, Python (SciPy), and LabVIEW for integration into experimental metadata workflows. Calibration documentation includes traceable uncertainty budgets aligned with ISO/IEC 17025:2017 guidelines. For GxP-regulated environments (e.g., pharmaceutical analytical labs), optional third-party validation packages—including IQ/OQ documentation, vibration transfer function (VTF) characterization, and audit-ready installation records—are available under FDA 21 CFR Part 11-compliant data governance protocols.
Applications
- Laser interferometry and gravitational wave detector prototype benches
- Confocal and super-resolution microscopy staging platforms
- Optical coherence tomography (OCT) and femtosecond laser delivery systems
- Atomic force microscopy (AFM) and scanning tunneling microscopy (STM) baseplates
- Quantum computing testbeds requiring ultra-low acoustic coupling
- Calibration laboratories performing ISO 10360-compliant CMM verification
FAQ
Is the DVIO-R platform suitable for vacuum chamber integration?
Yes—the 430 stainless steel top plate and oxide-treated carbon steel base are vacuum-compatible up to 10⁻⁶ Torr when properly baked out; however, the perimeter damping material is not rated for ultra-high vacuum and must be shielded or replaced per application-specific UHV requirements.
Can custom hole patterns or metric/imperial hybrid threading be specified?
Yes—DAEIL offers OEM configuration services including non-standard grid spacing, threaded inserts (e.g., M4, 10-32 UNF), and localized reinforcement zones for high-point-load instrumentation.
What is the typical first-mode natural frequency for a 200 mm-thick DVIO-R table loaded with 150 kg?
Empirical measurements show a fundamental flexural mode between 12–16 Hz depending on support stiffness and mass distribution; full modal analysis reports are supplied with each shipment.
Does the platform require periodic maintenance or recalibration?
No—being a passive mechanical structure, it requires only routine visual inspection of leveling feet and caster integrity; flatness verification is recommended every 24 months in GLP/GMP environments using certified autocollimators or digital levels.
