Minus K's FP-1
Negative-Stiffness Vibration Isolation Platform Supports Sems,
Tems And Large Metrology Systems
Specifically designed for SEMs (scanning electron
microscopes), TEMs (transmission electron microscopes)
and large metrology systems, the FP-1TM Negative-Stiffness
vibration isolation floor platform from Minus K®
Technology, Inc. enables low frequency vibration isolation
for weight loads from 500 lbs. to over 12,000 lbs.
The FP-1 can achieve natural frequencies of 0.5 Hz
or less, vertical and horizontal.
Negative-Stiffness isolators provide a unique and
completely mechanical concept in low-frequency vibration
isolation for the field of large load systems. In
particular, the transmissibility ? the vibrations
that transmit through the isolator? is substantially
improved over other systems, providing better isolation
performance without the need for air or electric power.
Also, substantial isolation can be provided for vibrations
as low as 1 and 2 Hz. Minus K has just announced the
standardization of their Negative-Stiffness SM-1TM
isolators, thus lowering the cost of the FP-1 platforms
making them more accessible to universities and laboratories
on tight budgets.
Minus K has had very good success with their FP-1 platforms
and SM-1 isolators. One installation of a Negative-Stiffness
FP-1 platform enabled a SEM on a badly vibrating second
floor to go from 100,000 magnification to 500,000 magnification
and revealed components of cotton fibers that could not
be seen previously.
A national laboratory replaced its air isolators with Negative-Stiffness
SM-1 isolators using its existing platform for an electron
microscope. Researchers marveled over being able to get
a high-resolution image and have it remain until the next
day. With actual results like these being reported, Minus
K has seen a dramatic increase in their SEM and TEM inquires.
The FP-1 platform typically utilizes two or three Negative-Stiffness
SM-1 isolators, as the basic building blocks of the platform.
Additional SM-1 isolators can be added to achieve higher
capacity systems. They can be arranged in many geometrical
configurations to suit varied application and customized
to achieve user-specific needs. For SEMs and some TEMs only
the column console is isolated or in some cases the column,
display and other components are isolated on the platform.
Customized SM-1 isolators were selected for the ground
testing of NASA's James Webb Space Telescope at the Johnson
Space Center. A major factor in selecting Minus K is its
ability to not only isolate vibrations vertically, but also
horizontally at less than 1 Hz. Minus K Technology works
with many instrument manufacturers and academic laboratories
providing custom systems and a line of standard bench top
and table vibration isolation products. Minus K has made
custom vibration isolation systems for NASA, JPL, DOD, European
Space Agency, German Space Center and the James Webb Space
Telescope (JWST) Project.
The company was founded in 1993 to develop, manufacture
and market state of-the-art vibration isolation products
based on its patented Negative- Stiffness technology. For
