Thorlabs active vibration isolation optical table supports contain an isolation system that effectively isolates the optical table from vertical and horizontal vibrations throughout the critical 3 to 50 Hz frequency range since most common large-amplitude sources of vibrations found in laboratories vibrate within this range of frequencies (see the Optical Tables Tutorial chapter on Sources of Vibration). The vertical vibrations are isolated from the optical table by a dual-chamber pneumatic isolation system that requires a constant source of compressed air. If the source of compressed air is removed, the optical table will lower until it securely rests on the large-diameter cylindrical optical table supports, albeit the table will no longer be isolated from floor vibrations. The horizontal vibrations are isolated from the optical table by mounting the vertical isolation system on a trifilar suspension system. This proprietary design eliminates the need to use oil-based damping systems that can leak or degrade over time. Each optical table support is also equipped with a 3-way valve. The valve regulates the pressure in the pneumatic isolation system to control the height of the optical table. If the table is displaced vertically, the 3-way valve will allow the pressure in the dual-chamber air reservoir to increase or decrease, as necessary, so that the table is returned to its original height. More information about the function and construction of the optical table supports can be found under the Design tab or in the chapters on Theory of Vibration Isolation and Optical Table Support Design.

When the active optical table supports are paired with a Nexus™ series optical table and setup in a quite environment even the most vibrationally sensitive photonics experiments like interferometry, holography, and nanopositioning can be preformed. In addition, the active optical table supports can be used to dramatically reduce the vibrations transmitted to an optical table setup in a noisy environment like on the upper floor of a steel framed building .

Tabletop Height
To accompany our two optical table thicknesses, 210 mm and 310 mm (8.3" and 12.2"), our optical table supports are available with heights of 600 mm and 700 mm (23.6" or 27.5") to produce a working height of 910 mm (35.8"). All our optical tables are clearly marked on the underside to show the ideal position of each isolator, and full installation instructions are included. A set of four isolators is capable of supporting loads up to 5500 lb (2500 kg) and is sufficient for use with tables up to 10' (3 m) in length. More than four isolators will be necessary for higher loads, longer tables, or custom-designed joined systems.
