This passive air-spring isolation Optical Table features all-steel construction, excellent thermal stability, and broadband damping optimized. The 5 mm thick stainless steel top and bottom skins have a precision-machined matte finish with surface flatness of ±0.1 mm over any 1 m2 area. The optical table has M6 mounting holes on 25 mm centers with a 37.5 mm border at the edge of the breadboard.


This optical table is constructed of 304L grade stainless steel. This alloy of steel contains less iron than typical stainless steel, which reduces its ferromagnetic properties. 304L steel is usually referred to as "virtually nonmagnetic" since weak magnetic properties are still present.


These air-spring isolators have a closed pneumatic isolation system that effectively isolates the optical table from floor vibrations throughout the 10 to 50 Hz frequency range. Most sources of vibrations in a lab are within this frequency range, thus these supports are suitable for use in many labs.


These isolators provide simple and effective passive vibration isolation with excellent stability. The closed pneumatic isolation system can be inflated with a simple pump or some other source of compressed air. These isolators do not require a constant source of compressed air to maintain isolation. If the pneumatic isolation system is depressurized, the optical table will remain securely supported on and slightly isolated by the reinforced rubber air mount of the optical table supports. Alternatively, if the air chamber is overinflated, vertical stops will prevent the optical table from rising above the maximum designed range. If the table is at either end of the range of motion, the optical table supports will no longer isolate the optical table from floor vibrations.
