Overview
The SM-1 negative-stiffness isolator is the basic building block of the FP-1 Floor Platform and other heavy multiple isolator systems.
This isolator has the same basic features of our all passive, negative-stiffness, manually-adjustable bench top isolators. It offers our very-low frequency isolation performance for payloads of many thousands of pounds.
If there is a need, the isolators can be customised to achieve user specific needs. For example, different horizontal and vertical frequencies, dampening, etc. They can also be made cleanroom and vacuum compatible.
