Active Vibration Isolation Optical Table
providing highly advanced vibration isolation
The DVIA-MO series is a combination of the DVIA-M active vibration isolation system with high-performance
optical table tops, which provides an absolute vibration controlled environment for photonics,
laser and spectroscopy requiring the low-frequency vibration isolation below 5 Hz.
Sub-Hertz Vibration Isolation Performance
The most sophisticated active vibration control algorithms are embedded in the DVIA-MO series,
delivering 50% - 80% vibration isolation at 1 Hz and and 90% vibration isolation at 2 Hz in six degrees of freedom.
Super Rigid Optical Table
Our optical tables are built to last forever, designed to be as stiff as possible to minimize relative motions
between existing optical elements that are mounted on the optical table.
Feedback & Feedfoward Control Algorithm
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.
Active Vibration Isolation in
All Six Degrees of Freedom
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).
50 – 80% vibration isolation at 1 Hz,
≥90% vibration isolation at ≥2 Hz.
