Hybrid Vibration Cancellation System

TMC – India has introduced a Hybrid Piezoelectric/Air Active Vibration Cancellation System, Stacis® iX LaserTable-Base™, the latest addition to its Stacis iX line of piezoelectric active vibration cancellation systems. LaserTable-Base offers an extraordinary level of improvement over existing technology in the amount of vibration isolation attainable with an optical table. Typically, optical tables are supported by low-frequency pneumatic vibration isolation systems. Though very effective at isolating high frequencies, these passive systems actually amplify vibration in the critical 1 to 3 Hz range. TMC’s Stacis technology overcomes these limitations through a patented technology which incorporates piezoelectric actuators and inertial vibration sensors to cancel, not amplify, very low frequency vibration. The Stacis iX LaserTable-Base combines these two technologies, air and Stacis, into one integrated cancellation system. The result is vibration cancellation at very low frequencies and unprecedented levels of high frequency isolation due to the combined effect of two isolation systems in series. Furthermore, the Stacis iX family improves upon the original STACIS technology by the addition of extended travel piezoelectric actuators (to accommodate even the worst floors) and a design that uses fewer actuators, significantly lowering total cost. The upper, pneumatic portion of STACIS iX LaserTable-Base is modular and interchangeable. It can incorporate TMC’s Gimbal Piston™ Air Isolators, MaxDamp® Air Isolators, or even rigid, non-isolating supports, depending on the application requirement.
