Application of active vibration insulated system AISOptimal vibration isolation performance for machines with high dynamic forces that are performing sensitive measurements and inspections, lithography equipment,laser machines, high resolution electron microscopes and machinery for the semiconductor industry. AIS has two primary functions; One function is to protect the precision machines from floor vibration. The other primary function is to improve the performance of the machines by minimizing structure borne vibration created by the high dynamic forces produced during an acceleration of deceleration of a moving mass within the machine. In addition, settling time is reduced which minimiaes the delay time before the machine can start performing its sensitive operation.
