Active Vibration Isolation


Vibration is undesirable in many measurement methods. Active vibration isolation involves sensors and actuators that cancel out incoming vibrations to prevent the transfer of vibrations to such systems. In today’s world of nanotechnology, optimal vibration isolation is absolutely essential for creating and analyzing very small structures. Therefore, our vibration isolation systems are the most effective solution to isolate your high-resolution measurement equipment from disturbing vibrations.

How does Active Vibration Isolation work?

To control vibration in all six degrees of freedom the system uses several active elements and a feedback mechanism. The active elements consist of a piezoelectric accelerometer, an analog output control, an electromagnetic transducer and a spring. The spring holds the weight of device on top of the active vibration isolation platform and helps isolating frequencies above 200 Hz. For lower frequencies the active part with feedback controls the isolation of the instrument on top. In this case the very sensitive piezoelectric accelerometer detects the external vibrations to the instrument which are fed back to the electromagnetic force transducer for compensation of the measured vibration levels at specific frequencies.

Why use Active Vibration Isolation?

Active vibration isolation is very important in today’s world of nanotechnology. It is essential for creating and analyzing very small structures. Our platforms manufactured by Accurion (Halcyonics) for active vibration isolation cancel out incoming vibrations to prevent the transfer of vibrations to any sensitive measurement system. This form of vibration isolation is undoubtedly the most effective solution to isolate high-resolution measurement instruments from disturbing vibrations. We offer a broad range of products for active vibration isolation.
