AVI-200-S
The basic configuration of the AVI 200-S includes two single elements and one control unit and can isolate actively up to max. load of 400 kg. Higher loads can be easily accommodated by increasing the number of isolation elements. To adapt the AVI 200-S to user specific applications, single elements in different lengths are available to special order.
Key Features
- The isolation of AVI 200-S begins at 1 Hz, increasing rapidly to 35 dB beyond 10 Hz
- The lack of any low frequency resonance means much better performance than with common passive air-damped systems
- The inherent stiffness of the AVI 200-S systems imparts excellent directional + positional stability
- The outstanding performance of the AVI 200-S includes all six translational and rotational vibration modes
Manufacturer
Table Stable
The Table Stable Ltd: the world leader in active vibration isolation, and in high resolution, high contrast spectroscopy. Low power piezoelectric technology combined with Swiss quality sets their products apart from the competition.
Performance
The transmissibility graph represents the vibration isolation performance of the AVI-200 Series over a frequency domain. The performance data is representative of all rotational modes of vibration (all six degrees of freedom) and should serve as a conservative estimate of performance customers can receive when pairing their instrument with an AVI-200 platform.

Applications
The AVI-200 platforms support a wide range of high-precision microscopes sensitive to low-frequency vibration noise. The most common application for the AVI-200 platforms is atomic force microscopy, supporting both end users and OEMs around the world by removing low-frequency vibration noise from important measurements.
In addition to AFMs, the AVI-200 platforms often support:
- Atomic Force Microscopy
- Interferometry
- Profilometry
- Tribology
- High Precision Metrology
- And More!
