Your electron microscope deserves zero disturbance.
The DVIA-ML doesn't just reduce vibration. It eliminates it. Advanced sensors detect floor disturbances as low as 0.3 Hz. Adaptive algorithms respond in 0.5 ms. And electromagnetic actuators generate the exact opposing force so your imaging stays flawless, every time.The DVIA-ML doesn't just reduce vibration. It eliminates it.

Nano-surface imaging without drift
Floor vibrations cause image drift and blur at magnifications above 50,000×. The DVIA-ML cancels disturbances from 0.5 Hz, keeping electron beams precisely on target for artifact-free SEM imaging.Floor vibrations cause image drift and blur at magnifications above 50,000×.

Magnets protected. Spectra preserved
Superconducting magnets at 600–1200 MHz are hypersensitive to building vibrations. Floor motion degrades shim stability and spectral resolution. The DVIA-ML isolates the entire magnet assembly from floor vibration at all frequencies.Superconducting magnets at 600–1200 MHz are hypersensitive to building vibrations.

Feedback corrects. Feedforward anticipates.
Feedback measures vibration on the isolated mass and counters it in real time. Feedforward reads the floor and cancels disturbances before they arrive. Together, they deliver exceptional low-frequency isolation. Your instruments operate as if the vibration doesn't exist.
How it works
Passive Isolation (Spring & Damper):
Without active controls, the spring (k) and damper try to absorb shocks. However, at low frequencies, they can actually amplify the floor disturbance (d), causing the mass to resonate.
Feedforward Control:
Leverages ground sensor data to proactively command the actuators, nullifying floor vibrations before they reach the isolated mass.
Feedback Control:
Continuously measures the isolated mass's residual vibration (y) and uses the actuators to counteract it in real time.
Together, these advanced control mechanisms significantly enhance isolation performance, keeping the mass nearly perfectly still!
