DVIA-MB Series

Active Vibration Isolation Platform for Ultra High-Resolution SEM, TEM, FIB and FIB/SEM and other analytical instruments

DVIA-MB is the ultimate base active vibration isolation platform for ultra-high-resolution electron microscopes. With exception low-frequency isolation performance, DVIA-MB enables high-performance electron microscopes to obtain high-resolution images of both biological specimens and materials samples. The DVIA-MB reduces vibrations in the critical range of 1 – 10 Hz where the electron microscopes are incredibly susceptible to low-frequency vibration.

DVIA-MB achieves its outstanding performance by using four active vibration isolators that utilize both air springs and active isolation technology. By using both actuators and air springs, the DVIA-MB system effectively isolates both high and low-frequency vibration.  The integrated sensors and actuators effectively reduce the low-frequency vibrations and start to isolate vibrations from 0.5 Hz, achieving 90% vibration isolation at 2 Hz and 99% at 10 Hz. Simultaneously the air springs support payloads from 500 kg to 6000 kg and effectively reduces high-frequency vibrations and lower the natural frequency.

As the images above clearly demonstrate, when low-frequency vibrations disturb electron microscopes, it is critical to reducing these vibrations to obtain nanoscale resolution images. DVIA-MB is the best solution for nanoscale imaging.

Unbeatable vibration isolation performance

The resonant frequency of active isolation systems is much lower than that of passive isolation systems. The active component of the DVIA-MB excels in controlling vibrations in the 1-10 Hz range.  Typical passive systems amplify the low-frequency vibrations rather than filtering them. DVIA-MB is highly effective in isolating ultra-precision instruments from the low-frequency vibrations that cause disruptions and instability.  Active vibration isolation starts at 0.5 Hz, with DVIA-MB delivering 90% at 2 Hz and 99% at 10 Hz.

Feedback & feed-forward algorithms

The DVIA-MB uses the feedback control system to continuously detect vibrations disturbing an isolated payload base and instantaneously react to minimize vibration in real-time. The feed-forward system is employed in the DVIA-MB to filter out floor vibrations in a predefined way.

Controlling vibrations in all six degrees of motion

Inertial sensors and electromagnetic actuators installed in the DVIA-MB active vibration isolation systems detect and control vibrations in three translational degrees of motion ( X, Y, and Z), and three rotational degrees of motion (pitch, roll, and yaw).

The DVIA-MB provides vibration-cancellation along all six degrees of freedom

On-site tuning for better performance

Vibration levels vary depending on the environment, location, vibration sources, and other factors. Therefore, VEC performs on-site tuning to guarantee the maximum performance level and your satisfaction. The engineer first conducts a site survey to measure vibration data.  VEC then analyzes and uses this data to tune the feedback and feedforward control systems to maximize vibration isolation performance.
