Peabody, MA. TMC has introduced the Everstill K-400 compact benchtop active vibration-cancellation system. The Everstill K-400 is suitable for small, lightweight, ultra-precision instruments, including optical microscopes, scanning-probe microscopes, and metrology instruments, helping those tools achieve superior resolution.
The patented Everstill starts to isolate at 0.7 Hz and delivers significant vibration cancellation, especially in the critical 1- to 10-Hz range. Everstill achieves that performance through an active “hard-mount” with serial-type architecture. The robust plug-and-play design requires no air.
“Serial-type active systems achieve better overall vibration isolation because payload resonances are mechanically filtered from the vibration sensors,” stated Wes Wigglesworth, product manager for active systems. “This allows for high gain settings with no sacrifice in system stability.”
He added, “Everstill’s vibration sensor is a geophone-type velocity sensor rather than a low-cost accelerometer, achieving a significantly lower noise floor, especially at low frequencies.”
TMC designs and manufactures precision vibration isolation systems for sensitive research and manufacturing processes worldwide. TMC is an ISO 9001:2008-certified company. Its products include active and passive vibration isolation systems; optical tops, optical table systems, and breadboards; laboratory tables and tabletop platforms; floor platforms; magnetic-field cancellation and electric field shielding systems; and acoustic enclosures.
TMC is a unit of AMETEK Ultra Precision Technologies, which develops ultra-precision measurement instruments and ultra-precise machine tools and manufacturing systems for the semiconductor, photovoltaic, nanotechnology, military, defense, and ophthalmic lens markets.
