Minus K's Education Giveaway
Minus K Continues Educational Giveaway
Minus K has again launched their educational giveaway for their negative-stiffness vibration isolators for colleges/univerities within the United States.
Any college/university within the United
States, that has an AFM, Electron Microscope, Interferometer,
Laser Optical System, Micro Hardness Tester, or any
other special equipment that would benefit from a
low-frequency vibration isolator can apply. No purchase necessary.
The submission forms will be judged by the Educational Giveaway Committee on multiple catagories.Limited to one submission per college department. Submission deadline for applications is February 29, 2016.
college departments will be notified by March 31,
2016 and posted on Minus K's website.
A new FREE Minus K vibration isolator will be shipped within one month of notification.
Minus K will conduct a brief interview with the selected departments six months after receiving their isolator. The interviews will be used to learn how vibration isolator helped with the application goals and interview may be used for articles in industry publications.
Congratulations to the education giveaway winners:
Purdue University – Chemistry Department
Vibration isolator for use with their custom-built scanning tunneling microscope (STM).
(The major research thrust of their group is the design of custom scanning probe instrumentation that provides structural resolution within single molecules at the sub-nanometer scale.)
Willamette University - Physics Department
Vibration isolator for use to frequency down-conversion of 846 nm light to 423 nm light in a home-built bow-tie cavity using a BiBO nonlinear crystal. The 423 nm light will be used to cool and trap calcium atoms. (The long term goal of this project is the generation of ultracold dipolar dimers consisting of one rubidium and one calcium atom. One exciting application of these molecules is their potential use in quantum computation.)

In manufacturing, CMMs are used to test a part or assembly against the design intent. By precisely recording the X, Y, and 2 coordinates of the target, points are generated which can then be analyzed for the construction of features. These points are collected by using a probe that is positioned, in this circumstance via direct computer control (DCC), DCC CMMs can be programmed to repeatedly measure identical parts. Hence, CMMs are a specialized form of industrial robot.
Vibration Isolation Critical
These high-throughput CMM laser interferometry surface measurement systems, however, can be negatively affected by plant low-frequency vibrations. which can distort the interferometry measurements and deliver inaccurate readings.
One of these CMM systems, custom-designed and manufactured for specific applications by Arnold Gauge Company, has resolved the vibration issue. The company's CMM system maintains its precision high throughput by integrating a unique, highly-compact Negative-Stiff ness vibration isolation platform.
"Every second, the laser in the CMM is generating about 2,000 readings per second," said Michael Bruins, President of Arnold Gauge Company. "These readings, taken at the micron level, are displayed on a chart, plotted against the pre-engineered ideal surface.
Due to these micro tolerances, any vibrations, whatsoever, on the plant floor, such as from forklifts, for example, are going to be detected in the readings, and will negate the validity of the results. To counteract these vibrations, we selected Negative-Stiffness vibration isolation.
Laser-based interferometers are extremely sensitive devices that are capable of resolving nanometer scale motions and features. They often have very long mechanical paths which makes them even more sensitive to vibrations. The sophisticated modern ellipsometry techniques that allow this high performance rely on low noise to be able to detect fringe movement. Properly isolating an interferometer will allow it to provide the highest possible resolution.
improved AFM performance. One of these advances has expanded the AFM ability to image biological samples in an aqueous buffer and provide a range of physical data for the sample. Another has increased the imaging speed of AFMs. Unlike Scanning Electron Microscopes, which are capable of scanning in near real-time, conventional AFMs, prior to about five years ago, required between one and 100 minutes to obtain a high-resolution image. With the introduction of high-speed AFM systems, imaging speeds are three orders of magnitude faster than with previous AFMs.
