Active Vibration Isolation - Antivibration AVI-400

AVI-400

Isolates in six possible rotational and translational modes of vibration.
Active Isolation from 1 Hz to 200 Hz. Passive Isolation beyond 200 Hz
No low frequency resonance means much better performance that a passive system.
500 times stiffer than passive system
Inherent stiffness imparts excellent directional and positional stability
Module length can be adjusted for specific applications
Module style allows system to adapt to specific sizes and loads, making it idea for a wide range of applications

This low profile modular system consists of a minimum of two modules and a separate controller.š Each module supports 880 lbs.š Module length can be adjusted for specific applications.š Applications include precision instruments such as coordinate measuring machines, UHV-SPM, SEM, and TEM.

The inherent stiffness of the AVI-400 imparts excellent directional and positional stability. The lack of a low frequency resonance means much better performance than with passive systems.tems.

The inherent stiffness of the AVI-400 imparts excellent directional and positional stability.

The AVI-400 isolates all six degrees of freedom.
