The DVIA-M is the most advanced built-in active vibration isolation system in the world, incorporated in various platforms and used as a built-in active vibration isolation system inside electron microscopes.
Sub-Hertz Vibration Isolation Performance
The most sophisticated active vibration control algorithms are embedded in the DVIA-M series, delivering 50% - 80% vibration isolation at 1 Hz and and 90% vibration isolation at 2 Hz in six degrees of freedom.
Built-In Active Vibration Isolation System
The DVIA-M active vibration isolators are designed as a built-in active vibration isolation system for nanoscale imaging equipment such as electron microscopes.

The DVIA series uses the Feedback control algorithm to continuously detect vibrations disturbing an isolated surface and instantaneously react to minimize the vibrations in real-time. The Feed-Forward control algorithm is employed in the DVIA Series to filter out floor vibrations in advance before the floor vibrations can be transmitted to equipment installed on the active vibration isolation systems.
The DVIA Series controls vibrations in three translational degrees of motions ( X, Y and Z) and three rotational degrees of motions ( pitch, roll and yaw).
