AVI-600-M
These easy to install isolators protect delicate high resolution measurement instrumentation against disturbing influences such as building vibrations and forces introduced directly into the equipment by the operator. The basic configuration of the AVI 600-M includes two compact units and one control unit and isolate actively up to a max. load of 800 kg. Support of higher loads can be easily achieved by increasing the number of compact units. To adapt the AVI 600-M to user specific applications, compact units in different lengths are available.
Key Features
- The isolation of AVI 600-M 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 damping approaches
- The inherent stiffness of the AVI 600-M systems imparts excellent directional and positional stability
- The outstanding performance of the AVI 600-M includes all six translational and rotational vibration modes
- The AVI 600-M compact units do not require any large tools for installation
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-600 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-600 platform.

Applications
The AVI-600 platforms support a wide range of high-load microscopes and other research instruments sensitive to low-frequency vibration noise. The most common application for the AVI-600 platforms is electron microscopy, where they have supported both scanning electron microscopes and transmission electron microscopes with great success. End users and OEMs around the world find the low-profile nature of the AVI-600 platforms favorable versus competing solutions as it simplifies the installation process and removes the need for persistent maintenance.
In addition to SEMs and TEMs, the AVI-600 platforms often support:
- Ultra-High Vacuum Scanning Probe Microscopes (UHV-SPM)
- Lithography tools
- High precision metrology tools
- Spectrometry instruments
- And More!
