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. This is ideal since most common large-amplitude sources of vibrations found in laboratories vibrate within this range of frequencies (see the Vibrations tab of the Optical Tables Tutorial).

When the active optical table supports are paired with a Nexus® series optical table and setup in a quiet environment, even the most vibrationally sensitive photonics experiments like interferometry, holography, and nanopositioning can be performed. 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 (see the Selection Guide tab).

Vertical Isolation

The vertical vibrations are isolated from the optical table by a dual-chamber pneumatic isolation system that requires a constant source of compressed air, such as an air compressor (sold separately). 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, and the table will no longer be isolated from floor vibrations.

Horizontal Isolation

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.

Self-Leveling Valves

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 Isolation Systems tab in the Optical Tables Tutorial.

Tabletop Height

To accompany our three optical table thicknesses, 210 mm (8.3"), 310 mm (12.2"), and 460 mm (18.1"), our optical table supports are available with heights of 450 mm (17.7"), 600 mm (23.6") and 700 mm (27.5") to produce a working height of 910 mm (35.8"). A set of four isolators is capable of supporting loads up to 2500 kg (5500 lbs) and full installation instructions are included. More than four isolators may be necessary for higher loads, long tables, or custom-designed joined systems. Please contact Tech Support to discuss your specific requirements.
