The portable 8000 series from Kinetic Systems Inc. uses active feedback to achieve high levels of vibration isolation for high-resolution instruments such as interferometers and photo-imaging microscopes. The tabletop unit actively damps vibrations from 1.0 to 1000 Hz and isolates all six translational and rotational modes of vibration, with a natural frequency of 0.7 Hz, producing no low-frequency resonance. The automatic leveling mechanism is microprocessor-controlled and adjusts to different loads without user intervention. Isolation begins at 1.0 Hz and increases to 40 dB at 10 Hz. The system measures 15.75 x 17.75 x 3 in., has a load capacity of 330 lb and weighs 40 lb. The company says that the standard aluminum model is 500 times stiffer than air tables and, for vibrations above 1000 Hz, provides passive vibration control. It produces a multiplexed signal for an oscilloscope to display vibration levels with and without isolation. It also is available with a ferromagnetic tabletop and mounting holes.
