Everstill™ K-400
Active Vibration Cancellation Benchtop Platform




Overview
Introducing Everstill™, TMC's latest breakthrough in advanced floor vibration control. The patented Everstill K-400 is a benchtop active vibration cancellation platform which incorporates a "serial type" active architecture. This combined with velocity sensors for enhanced low frequency sensitivity attains a dramatic level of low frequency vibration attenuation.

Designed to isolate ultra-precision instruments from building floor vibration down to below 1 Hz, the Everstill K-400 is ideal for optical microscopes, SPMs, and metrology instruments. With Gainmatch™ (patent pending), easily choose one of three gain settings to achieve optimal performance in your environment.

With technology evolving from TMC's STACIS® piezoelectric vibration cancellation, Everstill is an active hard-mount that cancels vibration starting at 0.7 Hz. Specifically designed for maximum low frequency performance, Everstill excels in the critical 1-10 Hz range where precision instruments tend to be the most sensitive.

The portable, compact design is ideally suited for easy installation on work benches and tables. The only input requirement is power from a standard AC outlet.

The Everstill™ Advantage

Superior low frequency performance. Starts to isolate at 0.7 Hz. Dramatic vibration cancellation, especially in the critical 1-10 Hz range

Patented active vibration cancellation technology. Ideal for small, lightweight,
ultra-precision instruments

Active hard-mount.
No air. Robust plug and play design

Advanced Vibration sensor technology. Incorporates geophone type velocity sensors for
sub-Hz performance. Better low frequency sensitivity than accelerometers.

Gainmatch™ (patent pending) to optimize performance. K-400 automatically selects one
of three active gain settings at start-up to match your environment. This feature is also
user selectable.
