Posted by Lee Mather, Associate Editor

CM-1 negative-stiffness vibration isolators support heavy payloads while reducing low-frequency vibrations. They deliver vertical natural frequency of 1/2 Hz or less, which can be achieved over the entire load range. Horizontal natural frequency is load-dependent. Capacity ranges for weight loads from 50 to 800 lbs are available to match vibration-sensitive instruments such as scanning probe microscopes, micro-hardness testers, profilers, interferometers, electron microscopes, or other imaging systems.

PRESS RELEASE

New Compact, Negative-Stiffness Vibration Isolator from Minus K Technology Reduces Low-Frequency Vibrations While Supporting Heavy Payloads

New CM-1 isolator can be combined into multi-isolator systems to support heavy payloads while taking up very little room, and using no air or electricity.

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 CM-1 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 50 to 800 lbs.

The CM-1 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. 1/2 Hz or less can be achieved at or near the nominal load.

As with all Minus K isolators, the CM-1 is completely passive, using no air or electricity. The new isolators can be combined into multi-isolator systems to support heavy payloads while taking up very little room themselves. The CM-1 isolators can be placed on pedestals to bring them to an appropriate height to retrofit existing air tables, enabling existing table top systems to achieve much better isolation.

If needed, the CM-1 isolators can be customized to achieve user-specific needs. For example, different horizontal and vertical frequencies, damping, etc. They can also be made cleanroom and vacuum compatible.

Weight: Approximately 26 lbs.
Dimensions: 7.875" W x 7.875" D x 8.5" H
