AVI Series Modular Active Vibration Isolators

AVI Series Modular Active Vibration Isolators

For large instruments or custom isolation requirements, Table Stable provide the TS series of modular active vibration isolators. Built with Table Stable’s industry-leading active isolation technology, the AVI series can provide isolation for room-scale instruments up to 9000 kg in weight. The AVI isolators feature a low-profile design ease installation, and require no persistent maintenance. Isolators are available in a range of sizes and load capacities to suit any application.


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.

Sub-Hertz Vibration Control

Table Stable have developed unique active isolation technology, capable of providing sub-hertz vibration isolation (starting at 0.5 Hz) in six degrees of movement. Using a combination of piezoelectric sensors, actuators, and control electronics, Table Stable’s vibration isolators can maximise the performance of SEMs, AFMs and other sensitive instruments. Multiple form factors are available, including plug-and-lay desktop platforms, and modular systems for larger equipment.

Active Isolation for High Performance

The active isolation technology developed by Table Stable isolates vibrations in all six rotational and translational modes of vibration. Table Stable is the industry leader in low-frequency isolation, able to provide active isolation from 0.5 Hz to 200 Hz, and passive isolation beyond 200 Hz.

The active isolation technology also improves performance between 0 – 5 Hz over a passive system, as there is no low frequency resonance.
