Overview Developed in 2007, VAIS-AMT series is Korea's first commercialized tabletop active anti-vibration system. It satisfies IEST's VC-G class of environment for anti-vibration system to accommodate Atomic Force Microscope (AFM), a device especially vulnerable to low-frequency vibration disturbance.
VAIS-AMT also removes resonance phenomenon of passive isolation systems with easier installation and operation procedures. Since the commercialization, VAIS-AMT's excellent capabilities and competitive price have been recognized by worldwide AFM manufacturers and utilized in various nano-measurement instruments.
Supported by metal coil springs, VAIS-AMT requires no compressed air supplier.
It can be conveniently transported and installed anywhere with electricity.
Utilizing feedback and floor feed-forward controls, VAIS-AMT has an excellent capability to prevent low-frequency vibration disturbance, a common issue with passive anti-vibration systems.
Three LED lights (Red, Green, Blue) on the front panel conveniently display the status on vibration environment changes and serviceability.
Digitally-controlled VAIS-AMT is designed for convenient self-diagnosis of operation-related malfunctions, such as the center of gravity changes.
AMTEK provides a remote real-time support for convenient performance diagnosis and technical support.
