Nano-surface imaging without drift
Floor vibrations cause image drift and blur at magnifications above 50,000×. The DVIA-M 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×.

Atomic resolution. Zero mechanical noise
HRTEM and STEM modes demand sub-angstrom stability. Building vibrations — even imperceptible ones — destroy lattice fringe contrast. The DVIA-M provides the mechanical silence these instruments require.HRTEM and STEM modes demand sub-angstrom stability.

Picometer topography. Tip stays true.
AFM measures surface topography by physical contact between cantilever tip and sample. Any relative motion becomes measurement noise. At sub-angstrom probe sensitivity, building vibration becomes the dominant error source. The DVIA-M removes the floor as a noise source so the cantilever sees only the surface.AFM measures surface topography by physical contact between cantilever tip and sample.

Outperforms. Everything.
Isolation from 0.5 Hz.
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!

Stage 1: Raw Input
Extremely subtle micro-vibrations are captured by the sensors. Due to their low amplitude, they are easily lost amidst ambient noise.
Stage 2: Hardware Amp
The DVIA-M unit applies analog gain to boost the entire signal. Both the desired low-frequency wave and the high-frequency noise are amplified.
Stage 3: Software Filter
Advanced digital algorithms isolate and retain only frequencies down to 0.3 Hz, entirely stripping away the noise to leave a clean, readable sine wave.
Detection from 0.3 Hz.
A hardware amplifier boosts low-frequency gain.
A digital filter refines the signal. Together, they extend
accurate detection and isolation down to 0.3 Hz.
Responds before you notice.
A floating-point DSP delivering 1800 MFLOPS
processes vibration data in real time.
Response time: 0.5 ms. By the time vibrations reach
your microscope, it's already been cancelled.
Detects the imperceptible.
11 Geophone velocity sensors with 2.55 V/in/s sensitivity and just 0.15% distortion. They capture low frequency vibrations other systems miss entirely so the DVIA-M can cancel what it can't ignore.
Six axes. Zero compromise.
The DVIA-M controls all six degrees of freedom. Three translational, three rotational. No vibration path goes uncorrected. Its algorithm decouples each axis independently, eliminating cross-coupling. Sub-micron translational and sub-microradian angular stability, maintained simultaneously.
Magnetically silent.
Less than 0.05 μT magnetic field. Electron beams are sensitive to the smallest magnetic interference. The DVIA-M is engineered to be magnetically silent — your beam stays true, your images stay sharp.

YIMOTECH Resonac Electronic Materials ZEISS Sigma 360 FE-SEM DVIA-ML1000 Installation Report
YIMOTECH ZEISS Sigma 360 FE-SEM DVIA-ML1000 installation report — the DVIA-ML1000 active vibration isolation platform was installed at Guangzhou for end user Resonac Electronic Materials, then re-tuned (2nd trial) and measured with the equipment Turned off. Against the Sigma 360 horizontal and vertical allowable vibration specification (mm/s² RMS, 1–100 Hz), the bare floor exceeded the limit on the vertical and front-to-back axes, while the DVIA-ML1000 platform passed on all three axes. The tuning request work order, the allowable vibration tables and the per-axis Autospectrum plots are published; no installation photographs were permitted at the site.

YIMO TECH Hitachi High-Tech SU7000 SEM DVIA-ML1000 installation report — the DVIA-ML1000 active vibration isolation platform was installed at Fuzhou for end user Fujian University of Technology, then tuned and measured with the equipment in the IDLE state. Against the SU7000 horizontal and vertical allowable vibration specification (µm pk-pk, 1–10 Hz), the floor and the DVIA-ML1000 platform both passed on the vertical, left-to-right, and front-to-back axes.

FST LAZIN LODAS-B18 Photomask Blank Inspection System DVIF-FB (241001R5) Installation Report — Post-Reinforcement Performance Verification
Installation report for the DVIF-FB-1000x2000x3000H vibration isolation platform (S/N 241001R5) in the 3rd floor cleanroom of the FST Osan plant, covering the performance verification measurement carried out after reinforcement work on the platform top plate. A LAZIN LODAS-B18 photomask blank inspection system is mounted on top. Measurement was performed with the equipment in the IDLE state against a 25 µm/s RMS (VC-B) requirement in both the horizontal and vertical directions. Before reinforcement all three axes exceeded the requirement; afterwards the vertical (Z) axis improved from 27.7 to 17.9 µm/s and the left to right (X) axis from 70.7 to 22.4 µm/s, both satisfying VC-B, while the front to back (Y) axis improved from 71.0 to 48.0 µm/s (32.4% reduction) but remained at the VC-A level. Per-axis before/after VC Curves for the DVIF-FB top plate and per-axis VC Curves measured on the upper equipment stage are published.
YIMO TECH Broadcast and Television Metrology Thermo Fisher Talos FIB-SEM DVIA-ML1000 Installation Report
Thermo Fisher Scientific Talos FIB-SEM at Broadcast and Television Metrology in Wuxi, China, delivered through the YIMO TECH channel — DVIA-ML1000 installation report for the 1st tuning trial, tuned on June 5, 2026 with the equipment turned on/IDLE. Vertically the floor measured 4.62 µm/s RMS at 15.5 Hz while the DVIA-ML1000 platform stayed at 0.11 µm/s; left to right it went from 0.71 to 0.14 µm/s at 4.5 Hz and front to back from 0.58 to 0.034 µm/s at 3.5 Hz, so every axis passed on both the floor and the platform. Because Thermo Fisher Scientific issues site-specific ambient vibration requirements from its own SE-Tools site survey, the applicable specification follows that survey report. The tuning request work order and the per-axis VC Curves, Autospectrum and Transmissibility plots from the UI program are published.
