Vibration Isolation Case Studies

Thermo Fisher Scientific Apreo 2C SEM at Fuyang University of Technology in Fuyang, China, delivered through channel — DVIA-ML1000 installation report for the 1st tuning trial, tuned and written up on June 22, 2026. The measurement summary classifies both the floor and the DVIA-ML1000 platform as VC-G on the vertical, left to right and front to back axes. 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, the per-axis Autospectrum, VC Curves and Transmissibility plots from the UI program, and the photograph of the Apreo 2C standing on the DVIA-ML1000 are published.

Kunshan DeKaiYiTe (Kunshan, China) ZEISS Sigma 360 SEM DVIA-ML1000 installation report — following installation the system was tuned and vibration was measured with the equipment in the IDLE state. On all three axes the floor fails the vibration specification while the DVIA-ML1000 active isolation platform passes. Per-axis Auto Spectrum plots and the client tuning request form are published.

DVIA-ML1000 installation report (serial 250718R2) for a Hitachi High-Tech FE-SEM (SU8600) at Ningbo University of Technology, Ningbo in China. Tuning was carried out on 2026.06.05, and vibration measurements were taken from the floor and on the DVIA-ML1000 across vertical, left-to-right and front-to-back axes.
