Vibration Isolation

For the increasingly sensitive, high-performance scientific instruments, it has become extremely important to effectively attenuate the floor vibration at the installation site in order to ensure the instrument performance.
JEOL offers an extensive lineup of active isolation systems specially designed to prevent any drop in performance due to floor vibration.

Principle of Active Isolation System

Vibration is detected by the sensor mounted above the instrument, triggering the actuator to output a force in the opposite direction to cancel the vibration.
This makes it possible to attenuate vibration amplification due to resonance, which cannot be avoided with a passive isolator. By performing the optimal tuning to match the unique vibration conditions at each installation site, the full performance of the Active Isolation system can be achieved, preventing any negative impact on instrument performance.

The vibration attenuation effect of the Active Isolation System suppresses the effects caused by floor vibration, providing sharp, clear images.

Built-in type Active Isolation System

This is an Active Isolation System that is installed as a replacement for the standard anti-vibration mounts of the instrument. The effects due to vibration are eliminated more effectively, without compromising the appearance or usability of the instrument.

Pit type isolation platform

For a high center-of-gravity instrument like an ultra high voltage electron microscope, the low-frequency floor vibrations are effectively eliminated by this system. Combining with an Active Isolation system, it is possible to achieve even higher vibration isolation performance.
