Low Frequency Vibration Isolation & Isolators

Compact Suspension Isolators with 1/2 Hz performance vertical for weight loads from 30 to 640 lbs. [3 or 4 units per system]

The CS-1 is a compact, 0.5 Hz, passive mechanical negative-stiffness vibration isolator. Like other Minus K Technology isolators, they use no air or electricity. It is the first standard sub-hertz isolators designed to be used in suspension, not compression. The isolator mounts above the intended payload and use a load rod to connect to it.

The CS-1 is a vertical only isolator. Horizontal isolation is be provided by the pendular load rod itself. The longer the load rod, the lower the horizontal resonant frequency will be [load rod varies according to customer needs].

The isolators upper mounting point can be customized to adapt to the customer’s needs. They can be used in small spaces where previously getting this level of vibration isolation, was simply not possible. The CS-1 is vacuum compatible, and can be modified to be up to UHV compatibility.

Performance

  • Vertical natural frequency of 1/2 Hz or less can be achieved over the entire load range.
  • There is NO horizontal isolation built in to the isolator. [horizontal isolation is provided by means of the load rod, designed for each application]
  • For use at near room temperature. [not cryogenically compatible]
 

The CS-1 isolators are to be used in either three or four isolator configurations to provide a properly constrained system (even though each isolator is vertical only).

The CS-1s load rods work with the other isolators to make a stable system that can provide levels of isolation, not available before in such a small package.
