Features

Plug-and-Play Installation – NO AIR REQUIRED

The VAIS-AMT Active Vibration Isolation system is designed for simple plug and play operation for most applications. The plug and play design does not require complex installation or routine maintenance.  Likewise, you will be happy to know there is NO Compressed Air required. Furthermore, users can operate the entire system at the push of 2 buttons after powering on: A) push AUTO LEVEL and the system levels the supported instrument even on uneven surfaces; then B) push Active Isolation to begin suppression of any incoming ambient vibration.  Yes, it’s that easy!

Control Vibration in all 6 Degrees of Freedom

Inertial sensors and VCM actuators that are installed in the active vibration isolation system detect and control vibrations in three translational degrees of motion ( X-Y-Z), and three rotational degrees of motion (pitch, roll and yaw).

Performance

VIBRATION ISOLATION EXPLAINED

Overcome Limitations of PASSIVE Isolation Systems

A passive isolation system normally has its natural frequency from 1.5 to 10 Hz in which vibrations with the low forced frequency coincides with the natural frequency, amplifying incoming vibrations rather than reducing them.

Our VAIS series overcome this weakness by lowering the natural frequency of the system down to the sub-hertz range.  Therefore,  the VAIS series is incredibly effective at controlling 1 – 5 Hz where vibration-sensitive tools tend to be unstable and disruptive and cannot yield optimal results. The VAIS series starts to reduce vibrations from 0.5 Hz, delivering 80 – 90% at 2 Hz.

As this Transmissability graph shows, the active system excels in controlling vibrations in 1-10 Hz range, where the passive systems amplify the low frequency vibrations rather than filtering them. The VAIS systems are highly effective in isolating ultra-precise microscopes and instruments from these low frequency vibrations where the precision instruments tend to be unstable and disrupted.

Suppress SUB-HERTZ Vibrations

The VAIS-AMT systems are highly effective in isolating ultra-precise instruments from ambient vibrations ranging from 1–10 Hz where vibration-sensitive precision instruments tend to be unstable and disrupted by vibration such that they cannot produce optimal results. The VAIS-AMT systems start to isolate at 0.6Hz, delivering ±99% of vibration isolation at 10 Hz. 

This single specification of what frequency the system begins isolation and when 90% and 99% isolation is reached are the most critical when comparing different solutions to determine the best performer.

Superior Stiffness Characteristics

The system stiffness or resistance of the platform to motion is a dramatic difference between Active Vibration Isolation Systems and Passive Vibration Isolation systems.  The isolated base platform does not fluctuate like the passive isolated base platforms. The active isolation systems effectively increase positional stability for setting up various applications on the platform.
