New Ultra-Thin CT-2 Low-Frequency Vibration Isolation Platform Adapts to Space Constraints in Critical Micro- and Nano-Microscopy

BETTER horizontal performance and MORE payload ranges

At just 2-1/2 inches in height, while isolating vibrations as low as 1 hertz, the new completely-passive Negative-Stiffness tabletop vibration isolation platform - developed by Minus K Technology - provides the industry's thinnest low-height, low-frequency isolator for optimizing space in critical microscopy and laboratory applications.

Press Release: Minus K Technology has announced the new ultra-thin, low-height model CT-2 passive isolator - the successor to the CT-1 offers better horizontal performance with additional payload ranges for heavier instruments. The completely passive tabletop unit is just 2-1/2 inches in height, yet delivers 1/2 Hz vertical natural frequency, and ~1-1/2 Hz horizontal natural frequencies - considerably more low-frequency vibration isolation performance compared to air tables and active systems. The CT-2 utilizes Minus K's breakthrough patented technology that led to a Laser Focus World 2019 Innovation Award

Minus K CT-1 Ultra-Thin Vibration Isolator
The new Negative-Stiffness CT-2 ultra-thin, low-height, low-frequency vibration isolation platform mitigates space constraints in microscopy applications.

"Vibration isolation options for microscopy instrumentation like scanning probe microscopes, interferometers and stylus profilers have been limited to systems of several inches or more in height, which for many labs can be too tall," said Erik Runge, Director of Engineering at Minus K. "This can make for tight working conditions, which limits employing adequate vibration isolation, and compromising the functionality of the instrumentation. The new CT-2 ultra-thin, low-height isolator solves this problem."

Negative-Stiffness isolators employ a unique and completely mechanical concept in low-frequency vibration isolation. They do not require electricity or compressed air. There are no motors, pumps or chambers, and no maintenance because there is nothing to wear out. They operate purely in a passive mechanical mode. The Negative-Stiffness CT-2 isolator achieves a high level of isolation in multiple directions. It has the flexibility of custom tailoring resonant frequencies vertically.

he transmissibility of the CT-2 is substantially improved over air and active isolation systems. When adjusted to 1/2 Hz vertical natural frequency, the CT-2 Negative-Stiffness isolator achieves approximately 93 percent isolation efficiency at 2 Hz; 99 percent at 5 Hz; and 99.7 percent at 10 Hz.

"With the increased sensitivity in instrumentation, particularly at the nanometer level, more precise vibration isolation technology was needed to deal with lower-frequency vibrations," added Runge. "Negative-Stiffness isolation, integral to the CT-2, was specifically designed to isolate these low-frequency perturbations without having to deal with compressed air or electricity."

Negative-Stiffness vibration isolation systems have become a growing choice for micro and nanotechnology microscopy applications. Not only are they a highly workable vibration solution, but they provide location flexibility and portability that other vibration isolation systems cannot.

Minus K CT-1 Ultra-Thin Vibration Isolator
Technology is winner of a Laser Focus World Innovator Award

CT-2 Ultra-Thin Low-Height Tabletop Vibration Isolation Platform

BETTER horizontal performance and MORE payload ranges
Successor to CT-1

Minus K CT-1 Ultra-Thin Vibration Isolator

The Compact Tabletop (CT-2) uses Minus K's patented breakthrough technology allowing for the best performance on the market in just a 2.5 inch tall isolation platform. This unit is an upgrade from Minus K's CT-1 and offers better horizontal performance with additional payload ranges for heavier instruments.

This is the thinnest, most portable and most user-friendly isolator ever offered that is capable of delivering this performance.more...:
  • Horizontal frequencies are weight dependent.
  • Horizontal frequency of ~1.25 Hz is achieved at or near the upper limits of the payload range.
  • At the lower payload weights the horizontal frequency will increase.
  • Vertical frequency is tunable to 0.5 Hz throughout the payload range.
