Active Vibration Isolation System 776-0200

  • small size
  • lack of any low frequency resonance
  • inherently stiff (500x greater than that of a 1 Hz passive isolator)
  • rapid recovery time from shock (10 ms)
  • no air required; no set up time & calibration necessary
  • includes all three axis
  • superior to any passive system
  • no electromagnetic pollution to upset delicate instruments
  • no heating up by strongly reduced consumption

776-0200 is a compact modular dynamic anti vibration system offering isolation against all six translational and rotational vibrations. This moderately priced dynamic vibration isolation system achieves in a very small volume better isolation than is possible with the biggest and most expensive passive systems. Inertial feedback is used via force transducers to provide not only isolation from building vibrations, but also isolation from vibration sources placed on the system itself. This means, for example, that a delicate microscope isolated by the system will remain at rest despite forces being applied via the operator’s hands. The inherent stiffness of the system, typically 500 times greater than that of a 1 Hz resonance passive isolator, imparts excellent directional and positional stability. The lack of any low frequency resonance, a resonance which plagues all passive systems, allows the systems to be stacked for super-isolation in severe environments. The system is ideal for supporting delicate Fabry-Perot interferometers and tunnel-microscopes, allowing the ultimate performance to be achieved from these and other high resolution instruments. The tables have also proved to be extremely successful for supporting sensitive experiments, such as the troughs for liquids used in measurements on Langmuir-Blodgett films.

776-0200 is an adaptable system consisting of two modules. Each module by itself isolates against vertical and horizontal translations and against rotations about one horizontal axis. The combination of two modules isolates against all six possible translational and rotational vibrations. The modules cannot be used separately. Isolation of the standard 776-0200 system begins at about 1 Hz, increasing rapidly to at least 35 dB beyond 10 Hz. This system offers excellent isolation in the typical laboratory environment.
