SuperDamp™ Non-Magnetic self leveling vibration isolators offer thehighest performance of any pneumatic isolator, combining extremelylow transmissibility with excellent low frequency performance.

Vertical vibration is the most obvious factor that effects optical experiments; however, significant horizontal vibration is often encountered in laboratories on upper floors of buildings. Applications that demand extreme stability, such as interferometry, holography, and nanopositioning, require both vertical and horizontal isolation.SuperDamp™ self leveling isolators are large diameter free-standingsystems that provide maximum stability and safety, without cumbersome tie bars. The low vertical and horizontal transmissibilityof these isolators results in the least possible relative tabletop motion.Our proprietary design uses no liquids that could leak or degrade over time. Self Leveling System To allow for changes in load distribution, SuperDamp™ isolatorsalso feature a self leveling system that incorporates precision threewayvalves that do not compromise vertical isolation when the system is at rest. Because these valves are actuated by tabletop movement, the system returns to its original level position within ±0.25mm (0.01") after disturbances. The valves also automatically compensatefor any changes in tabletop load distribution.Additionally, this system allows the table height to be adjusted over arange of 26mm (1.02") and can be used to compensate for an uneven floor. SuperDamp™ isolators require a constant supply of air. When the air supply is removed, the tabletop rests securely on topof the legs with the isolation system disabled.

â–  Designed Specifically for Non-magnetic Applications SuperDamp™ TechnologyVertical Damping is achieved by the use of a dual chamberdamped pneumatic spring. The table is supported by the airpressure in these chambers. A piston, clamped to the bottomof the table, is sealed to the upper chamber with a rolling rubber diaphragm, allowing virtually friction free motion between piston and chamber. Floor or tabletop motion forces air to flow from onechamber to the other through a high resistance damper. Thisrestriction of airflow damps oscillatory motion between the floor and table, dramatically reducing settling time. The volume ratio of the chambers has been optimized to maximize damping performance for our complete range of tabletops while preservinga low resonant frequency. Horizontal Damping is accomplished by supporting thepneumatic vertical isolator on a trifilar suspension system. This innovative pendulum design uses gravity to provide the restoring force after horizontal disturbances. Horizontal oscillations at the system’s resonant frequency are damped by linking the base of thevertical isolator to the outer cylinder with an oil free vibrationabsorbing damper.
