MK52 Negative‐Stiffness Optical Table Isolation System Features/Benefits: Ultra‐low natural frequencies Vibradamped frame Customizable accessories Choice of tabletops Ergonomic style Class 100 cleanroom compatible Introducing the MK52, the New Optical Table for ultra‐low natural frequency applications. The Kinetic Systems MK52 Optical Table utilizes two Minus K patented negative‐stiffness vibration isolators to provide a passive optical table with ultra‐low natural frequencies, higher internal structural frequencies, and excellent vertical and horizontal isolation efficiencies. The Minus K vertical isolators use a stiff spring and a negative‐ stiffness mechanism to achieve a low net vertical stiffness without affecting the static load supporting capability. Horizontal isolation is provided by beam columns connected in series with the vertical‐ motion isolator. Adjusted to a 1/2 Hz natural frequency, the table achieves 93% isolation efficiency at 2 Hz, 99% at 5 Hz, and 99.7% at 10 Hz. Tables over 5' The 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. The premiere choice for large applications requiring high resolution such as: Raman spectroscopy, atomic force microscopy (AFM), AFM‐Raman integration, and micro‐hardness testing.
