Scanning Electron Microscopy
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.

Atomic Force Microscopy
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!

for nanoscale precision.
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.
