The totally passive mechanical system of negative-stiffness gives high precision vibration isolation and is now competing with traditional pneumatic air tables as the go-to choice for cleanrooms For decades, pneumatic air tables have been the workhorse for reducing vibrations in cleanrooms for manufacturing and research, where critical micro-engineering instrumentation is employed. But just as technology has steadily pushed the boundaries into nano-applications in microelectronics fabrication, industrial laser/optical systems and biological research, so has the need become ever more necessary for improved precision in vibration isolation. Increasingly, pneumatic air tables are taking a back seat to the more recent technology of negative-stiffness vibration isolation, which over the past 20 years since its introduction, has proven itself in thousands of applications throughout industry, government and academia, including some of the most diverse and challenging environments, such as cleanrooms.
