"VAIS-PMT is the world's exclusive pneumatic active anti-vibration isolator integrated with anti-noise chamber. Nano scale measurement instruments are vulnerable not only to floor structural vibration, but also to acoustical vibration and air flow. The VAIS-PMT's active anti-vibration system and anti-noise shield system effectively eliminate such factors.
VAIS-PMT provides consistently stable vibration environment with pneumatic active anti-vibration frame against even aperiodic impulse vibration input. Anti-noise chamber with multi-layer soundproof walls block air-flow nearby HAVC equipment and noise."
(1) Structure-borne noise (vibration) has comparatively longer wave length and stronger energy, which makes it especially important to isolate them.
(2) While air-borne vibration and acoustical vibration(noise) transmit smaller energy to the target instruments, they are transmtted directly to a microscope's measurement spot and greatly distort microscope image.
Air flow from nearby HVAC systems also greatly affects the microscope.
(3) VAIS-PMT single-handedly prevents floor vibrations, air-borne noises and air-flow for optimal nano-scale measurement."

1. Pneumatic Support Frame
The pneumatic support frame further strengthens VAIS-PTs robustness against aperiodic impulse vibration.
2. Floor Feed-Forward Control
Utilizing feedback and floor feed-forward controls, VAIS-PT has an excellent capability to prevent low-frequency vibration disturbance induced by the structural resonance of the building.
3. LED Status Indicator
Three LED lights (Red, Green, Blue) on the front panel conveniently display the status on vibration environment changes and serviceability.
4. Digital Control System
The digital controller provides a convenient user interface, setup parameter modification, and system diagnosis.
5. Remote Support
AMTEK provides a remote real-time support for convenient performance diagnosis and technical support."
