DVIA-T
Tabletop Active Vibration Isolation System
Sub-Hertz Active Cancellation. Portable. Zero Compressed Air.
The DVIA-T brings 6-degree-of-freedom active vibration cancellation directly to your benchtop. Starting at 0.5 Hz. With absolutely zero compressed air. It's the ultimate foundation for nanoscale metrology. Plug it in. Tune out the world.
The world's highest performance.
Passive air tables amplify low-frequency noise. Competing active systems struggle to keep up. The DVIA-T outperforms them all, delivering the most aggressive vibration cancellation profile on the market. Engineered with hyper-sensitive inertial velocity sensors and frictionless electromagnetic actuators, it doesn't just react to vibration. It dictates the environment faster than any platform in its class. The internal controller processes floor motion in real-time, instantly generating a precise counter-force to neutralize building sway before it ever reaches your instrument. The metrics prove the dominance. Active cancellation starts at an industry-leading 0.5 Hz. Isolation efficiency shatters the 90% threshold at just 2 Hz. Full 6-Degree-of-Freedom control guarantees absolute spatial stability.
True plug-and-play. Active isolation without the hassle.
The DVIA-T delivers a true plug-and-play active isolation system engineered for absolute user autonomy. We designed the complexity completely out of the equation. Simply connect a standard AC power cable, position your instrument, and press two buttons: Auto-Leveling, then Active Isolation. With no pneumatic lines to route and no complex PID parameters to tweak, the onboard intelligent controller takes over instantly. It automatically maps your payload's mass and locks in the optimal active feedback loop. You secure a world-class, sub-hertz isolation foundation with zero installation downtime, achieving total environmental control in under five minutes.
Precise automatic leveling with ±0.05 mm repeatability
The platform utilizes an automatic leveling function to instantly establish precise structural alignment whenever a payload is placed or replaced. Delivering ±0.05 mm repeatability, this feature eliminates manual calibration during instrument changeovers, ensuring continuous workflow efficiency and immediate operational readiness.
Compact & Portable: 420 × 500 × 95 mm
The DVIA-T delivers advanced active vibration isolation in a 25 kg tabletop design. It is fully plug-and-play. Simply place it on a standard bench, connect it to power, and it immediately establishes a stable foundation for your instruments—no compressed air or complex installation required.

Feedback corrects. Feedforward anticipates.
Feedback measures vibration on the isolated mass and counters it in real time. Feedforward reads the floor and cancels disturbances before they arrive. Together, they deliver exceptional low-frequency isolation. Your instruments operate as if the vibration doesn't exist.
How it works
Passive Isolation (Spring & Damper):
Without active controls, the spring (k) and damper try to absorb shocks. However, at low frequencies, they can actually amplify the floor disturbance (d), causing the mass to resonate.
Feedforward Control:
Leverages ground sensor data to proactively command the actuators, nullifying floor vibrations before they reach the isolated mass.
Feedback Control:
Continuously measures the isolated mass's residual vibration (y) and uses the actuators to counteract it in real time.
Together, these advanced control mechanisms significantly enhance isolation performance, keeping the mass nearly perfectly still!
