New CT-10 Ultra-Thin, Compact Low-Height, Low-Frequency Vibration Isolation Platform Adapts to Space Constraints in Critical Micro- and Nano-Microscopy
The new ultra-thin, low-height model CT-10 passive isolator – the more compact than the CT-2 to fit in much smaller spaces at just over 12 ½ inches square. The completely passive tabletop unit is 2.7 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-10 utilizes Minus K's breakthrough patented technology that led to a Laser Focus World 2019 Innovation Award. “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-10 isolator achieves a high level of isolation in multiple directions. It has the flexibility of custom tailoring resonant frequencies vertically. The transmissibility of the CT-10 is substantially improved over air and active isolation systems. When adjusted to 1/2 Hz vertical natural frequency, the CT-10 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-10, 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 Technology Announces Announces Its Ninth Educational Giveaway of Vibration Isolators to U.S. Colleges and Universities
With over thirty years in business, Minus K Technology has had the privilege of working with businesses, universities and laboratories all over the world, supplying superior passive mechanical vibration isolation products for research within universities, aerospace, audio reproduction, crystal growth, neuroscience, biology, chemistry, physics and a number of other fields. In acknowledgement that academia is the key to these industries, Minus K is giving away $25,000* dollars worth of their patented superior performing negative-stiffness low-frequency vibration isolators to colleges in the United States. These vibration isolators are used with AFM, Electron Microscope, Interferometer, Laser Optical System, Micro Hardness Tester, or any other special equipment that would be assisted by passive mechanical vibration isolation, Recipients of a Minus K isolator will be chosen based on the proposed use and applicability of the isolators. Deadline to apply is February 28, 2025. Winners will be notified via email and will also be posted on Minus K’s website (www.minusk.com). Past giveaway winners include: Arizona State University, California Polytechnic State University San Luis Obispo, University of Michigan, City University of New York, Irvine Valley College, Northwestern University, Purdue University, Saint Louis University, Saint Olaf College, Spokane Community College, Stanford University, University of California, Berkeley, University of California Davis, University of California Merced, University of Rochester, University of Tennessee, University of Texas at Dallas, Washington University in Saint Louis, Willamette University.
