Minus K Technology, a leading manufacturer of passive vibration isolation products, has just released a compact, high-capacity, low-frequency negative-stiffness isolator designed to support heavy payloads while reducing low-frequency vibrations.

The new LC-4 isolator comes in several capacity ranges to match vibration-sensitive instruments such as SPMs (AFMs, STMs, etc), micro-hardness testers, profilers, interferometers, electron microscopes, or other imaging systems, for weight loads from 1 to 130 lbs.
The LC-4 comes in two versions (Low Freq. Horiz and Ultra Low freq. Horiz.). Both can deliver a vertical natural frequency of 1/2 Hz or less, which can be achieved over the entire load range. Horizontal natural frequency is load dependent. The Low Freq. version has a 1 1/2 Hz natural frequency, while the Ultra Low version can achieve 1/2 Hz or less near the nominal loads.
As with all Minus K isolators, the LC-4 is completely passive, using no air or electricity. The new isolators can be combined into multi-isolator systems to support heavier payloads while taking up very little room themselves. The LC-4 isolators can be placed inside OEM equipment as needed enabling the systems to achieve much better isolation.
If needed, the LC-4 isolators can be customized to achieve user-specific needs. For example, different horizontal and vertical frequencies, damping, etc. They can also be made cleanroom or vacuum compatible.
