AVI-200 Series

This moderately priced dynamic vibration isolation system achieves in a very small volume better isolation than is possible with the biggest and most expensive passive systems. Inertial feedback via force transducers is used to provide not only isolation from building vibrations, but also isolation from vibration sources placed on the system itself. This means, for example, that a delicate microscope isolated by the system will remain at rest despite forces being applied via the operator's hands. 

The inherent stiffness of the system, typically 500 times greater than that of a 1 Hz resonance passive isolator, imparts excellent directional and positional stability. The lack of any low frequency resonance, a resonance which plagues all passive systems, allows the systems to be stacked for super-isolation in severe environments. 

The AVI-200/LP series is an adaptable system consisting of two modules and is ideal for supporting delicate Fabry-Perot interferometers and tunnel-microscopes, allowing the ultimate performance to be achieved from these and other high resolution instruments. 
This system offers excellent isolation in typical laboratory environments.

The AVI-200 Series active vibration isolation systems are available in 3 different sizes

 Model Dimensions (LxWxH) Load per unit Weight per unit
AVI-200-S 360 x 120 x  112,5 mm³ 200 kg 8 kg
AVI-200-M 600 x 130 x  112,5 mm³ 200 kg 10 kg
AVI-200-XL 820 x 130 x  112,5 mm³ 200 kg 12.3 kg
The default configuration of a AVI-200/LP isolation system consists of 2 vibration isolation units, allowing for a load of 400kg. Each module by itself isolates against vertical and horizontal translations and against rotations about one horizontal axis. The combination of two modules isolates against all six possible translational and rotational vibrations. Isolation of the standard AVI-200/LP system begins at about 2Hz, increasing rapidly to at least 35dB beyond 10Hz. 
Paired with the LFS-3 the AVI-200/LP active vibration isolation units can even go down to an isolation frequency of 0.7Hz.
Isolation performance is controlled by a A2CU controller unit. If the customer application requires greater load capabilities or has a larger instrument footprint more isolation units can be added.
