A key addition to Chamber A was the addition of a set of six custom 10,000 lb. capacity Minus K Technology's negative-stiffness vibration isolators. The Minus K passive isolators do not require air and offer better isolation than air and active isolation systems. A major factor in the selection of the of the vibration isolators was that they not only isolate vibration vertically, but also horizontally at less than 1 Hz. The isolators utilize Minus K's patented Thermal Responsive Element (TRE) compensator device, a passive mechanical device, requiring no air or electricity just like the isolators. The TRE compensator adjusted the isolators as the temperature changes throughout the testing at JSC, keeping the JWST in the proper position. The Critical Design Review for Spacecraft-to-Optical Telescope Element vibration isolation system was completed one month earlier than scheduled at the end of 2011. The six Minus K negative-stiffness vibration isolators were installed on top of Johnson Space Center's Thermal Vacuum Chamber A in March 2014. Engineers installed a massive steel platform suspended from the six vibration isolators via steel rods about 60 feet long (18.2 meters) each and about 1.5 inches (or 38.1 mm) in diameter, to hold the telescope and key pieces of test equipment.
The MK52 Series Vibration Control Optical Table with more ergonomic comfort is designed specifically for ultra-low natural frequency applications. The system utilizes Minus K's patented negative stiffness vibration isolators to provide a compact, passive optical table with ultra-low natural frequencies, higher internal structural frequencies, and excellent vertical and horizontal isolation efficiencies. It also does this without any air or electricity! The premier choice for large applications requiring high resolution such as: Raman spectroscopy, atomic force microscopy (AFM), AFM-Raman integration, and micro hardness testing. The MK52 Series can be configured for a wide variety of applications and customized with most of our vibration isolation workstation accessories. - Ultra-Low Natural Frequencies - Vibradamped Frame - Customizable Accessories - No Air Supply Needed - Easy to Use - Choice of Tabletops - Ergonomic Styling Table top options include Granite, Steel, Composite & Honeycomb. The MinusK vertical isolator uses a stiff spring and negative-stiffness mechanism to achieve a low net vertical stiffness without affecting the static load supporting capability. Horizontal vibration isolation is provided by beam columns connected in series with the vertical-motion isolator. Adjusted to a 1/2 Hz natural frequency, the workstation achieves about 93% isolation efficiency at 2 Hz, 99% at 5 Hz and 99.7% at 10 Hz. The MK52 Series optical table can be designed for a wide variety of applications and customized with auxiliary work surfaces, enclosures, shelves, seismic restraints, retractable casters, and many other options. Typical Vibration Control Applications for the MK52 Vibration Isolation Workstation: The MK52 Series is the premier choice for large applications requiring high resolution such as: Raman spectroscopy, atomic force microscopy (AFM), AFM-Raman integration, and micro hardness testing and other sensitive equipment in fields such as semiconductor processing, telecommunications, aerospace engineering, and medical research. Manufactured in conjunction with Kinetic Systems. For International Orders, A Handling Fee of 5% is Added. Contact Minus K for custom payload ranges and sizes.

Compact Suspension Isolators with 1/2 Hz performance vertical for weight loads from 30 to 640 lbs. [3 or 4 units per system] The CS-1 is a compact, 0.5 Hz, passive mechanical negative-stiffness vibration isolator. Like other Minus K Technology isolators, they use no air or electricity. It is the first standard sub-hertz isolators designed to be used in suspension, not compression. The isolator mounts above the intended payload and use a load rod to connect to it. The CS-1 is a vertical only isolator. Horizontal isolation is be provided by the pendular load rod itself. The longer the load rod, the lower the horizontal resonant frequency will be [load rod varies according to customer needs]. The isolators upper mounting point can be customized to adapt to the customer's needs. They can be used in small spaces where previously getting this level of vibration isolation, was simply not possible. The CS-1 is vacuum compatible, and can be modified to be up to UHV compatibility. - Compact suspension loaded isolator - Individual capacities 10 to 160 lbs. - 0.5 Hz Vertical Natural Frequency - Room temperature - vacuum compatible - Combined into multi- isolator systems to support heavy payloads from 30 - 640 lbs [3 or 4 units per system] Weight: Approximately 4.4 lbs.

(55.4– 72.7 kg) $3,550 Performance - Vertical natural frequency of 1/2 Hz or less can be achieved over the entire load range. - There is NO horizontal isolation built in to the isolator. [horizontal isolation is provided by means of the load rod, designed for each application] - For use at near room temperature. [not cryogenically compatible] The CS-1 isolators are to be used in either three or four isolator configurations to provide a properly constrained system (even though each isolator is vertical only). The CS-1s load rods work with the other isolators to make a stable system that can provide levels of isolation, not available before in such a small package.

The new MK26 Series Vibration Control Workstation with more ergonomic comfort is designed specifically for ultra-low natural frequency applications. Kinetic Systems manufactures the system utilizing the Minus K patented negative stiffness vibration isolators in order to provide a compact, passive Vibration Isolation Workstation with ultra-low natural frequencies, higher internal structural frequencies, and excellent vertical and horizontal isolation efficiencies. The MK26 has also been upgraded to provide much better user comfort and additional leg space. The Minus K vertical isolator uses a stiff spring and negative-stiffness mechanism to achieve a low net vertical stiffness without affecting the static load supporting capability. Horizontal vibration isolation is provided by beam columns connected in series with the vertical-motion isolator. Adjusted to a 1/2 Hz natural frequency, the workstation achieves 93% isolation efficiency at 2 Hz, 99% at 5 Hz and 99.7% at 10 Hz. The MK26 Series can be configured for a wide variety of applications and customized with most of our vibration isolation workstation accessories. Typical Vibration Control Applications for the MK26 Vibration Isolation Workstation The MK26 Series offers the ultimate performance for a wide range of instruments, such as analytical balances, cell injection, confocal microscopes, patch clamping, optical microscopes, wafer probing, sensor calibration atomic force microscopes and other sensitive equipment in fields such as semiconductor processing, telecommunications, aerospace engineering, and medical research.

Low frequency vibration isolator for weight loads from 15 to 130 lbs. and 1/2 Hz performance vertical and horizontal. Minus K's LC-4 is an ultra compact, low-frequency negative-stiffness isolator. It comes in two configurations, our low horizontal frequency performance of 1.5 Hz or our ultra low horizontal frequency performance of 0.5 Hz. Both configurations offer our signature 0.5 Hz vertical natural frequency. The LC-4 isolators can be combined into multi isolator systems to support heavier payloads while taking up very little room themselves. The isolators are passive, manually-adjustable and require no air or electricity. If needed, the LC-4 isolators can be customized to achieve user specific needs. Eg., different horizontal and vertical frequencies, damping, etc. They can also be made cleanroom and vacuum compatible. For International Orders, A Handling Fee of 5% is Added.
