Minus K Technology negative-stiffness
vibration isolators available
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.
Minus K Technology
|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
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"
