Vibration isolator reduces low-frequency vibrations

Negative-Stiffness vibration isolators can easily support the heavy weight of a combined 
AFM/micro-Raman system, and isolate it from low frequency vibrations more effectively than 
high-performance air tables or active isolation systems.

The Compact, high-capacity, low-frequency negative-stiffness isolator is 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, micro-hardness testers, profilers, interferometers, electron microscopes and other imaging systems, for weight loads from 1 to 130 lbs.

Available in two versions, both can deliver a vertical natural frequency of 0.5 Hz or less, which can be achieved over the entire load range. The isolator is completely passive, using no air or electricity, and can be combined into multi-isolator systems to support heavier payloads while taking up very little room itself (4.75” wide x 4.75” deep x 7” high). Can be placed inside OEM equipment as needed, and can be customized to be cleanroom or vacuum compatible. Minus K Technology, Inc.
