Vibration Isolation Case Studies

DVIA-ML1000 installation report (serial 230320R1) for a Hitachi SU8700 FE-SEM at Shanghai Jiao Tong University, Shanghai, China. Overview states the platform is appropriately installed and functioning as intended. Vibration specification is given as a diagram; tuning request N/A; measurement summary compares floor vs DVIA-ML1000 with equipment turned on/IDLE; UI-program VC, autospectrum, and transmissibility plots per axis; equipment photo; Reference uses the standard Generic Vibration Criteria markdown table.

DVIA-ML1000 installation report — Hitachi FE-SEM SU8700 (serial 230320R1) at Shanghai Jiao Tong University, Shanghai. Overview states the platform is appropriately installed and functioning as intended. Vibration specification is shown as the specification figure in the form; Measurement Summary PASS for floor versus DVIA levels by axis at 3.15 Hz aligned with the table in the source report. VC / Autospectrum / Trans plots from the UI program, onsite equipment photo, and the standard VC criterion table published as Markdown in Reference.

DVIA-M1000 installation report — Hitachi FE-SEM SU8600 (serial 250320R3) at Shanghai Jiao Tong University, Shanghai. Overview states the platform is appropriately installed and functioning as intended. The vibration specification appears as the uploaded specification figure, paired with the Measurement Summary VC levels by axis. Equipment condition, VC / Autospectrum / Trans plots from the measurement UI program, PASS lines in the summary table (matching the report), equipment photo; Reference uses the standard Generic Vibration Criteria markdown table.

DVIA-ULF700 (serial 250902R6) retuning report: TESCAN CLARA FE-SEM in Beijing, China, end user NAURA Technology Group. 2nd tuning (1st 2025-12-10); tuning and report date 2026-04-13. Publishes vibration-specification diagram, tuning-request UI capture, nine-axis VC / autospectrum / transmissibility plots, RMS measurement summary with pass/fail, and markdown VC reference (EMF omitted).

DVIA-ULF700 (S/N 251224R5) active vibration isolation platform installation report for a ZEISS Sigma 360 FE-SEM at East China University of Science and Technology (Shanghai, China). Vibration specification and tuning-request program captures, nine-axis UI plots (VC, Autospectrum, Transmissibility), and equipment photographs. Floor measurements FAIL vs PASS on isolator per the report summary table.

Nanjing Hangpu (Nanjing City) ZEISS Sigma 360 DVIA-ULF700 installation report — retuning was performed to restore performance that had degraded, and vibration measurement verified the results. After retuning the Vertical axis passed on the DVIA-ULF700 (FAIL on floor), and Left-to-Right and Front-to-Back passed on both floor and platform. Per-axis Autospectrum data and an installation photo are published.
