TMC’s Active Vibration Isolation Table features state-of-the-art vibration isolation performance. By integrating our new Compact Sub-Hertz Pendulum Isolation System (CSP ^®) for horizontal vibration reduction with our new PEPS-VX^® Inertial Damper for vertical vibration cancellation, we have produced a superior, ultra-quiet table in six degrees-of-freedom. This advanced isolation technology may be combined with TMC optical tables and other TMC products, as well as designed into equipment for OEM applications.

Detail Installation Featuring 10 dB of isolation vertically and 20 dB of isolation horizontally at 2 Hz (a frequency at which other tables amplify vibration), the Active Vibration Isolation Table is ideal for the most demanding applications in unusually severe vibration environments.
