About ClearDrop Technology
ClearDrop Technology is the optical surface-cleaning business associated with French company VISION SAS. Its device uses acoustic waves along a protective surface to remove water and other contamination without mechanical wiping. The company targets sensor optics on drones, naval equipment, surveillance systems and other platforms. Official programme records place ClearDrop in NATO DIANA’s 2026 maritime cohort, the COVE-hosted cohort and PortXL’s 2026 dual-use group; these records establish participation rather than system qualification.
Operating context
ClearDrop places an electronic acoustic device behind protective glass and drives surface vibration to move contamination. The company names rain, condensation, sea spray, muddy water, snow, frost, sand and dust among the intended cleaning problems. DIANA describes a nanoscale transducer acting through the sensor surface; quantitative power, dimensions, coating compatibility and environmental limits remain unestablished in the reviewed public material.
