ClearDrop uses a small electronic device behind protective glass to propagate acoustic waves along its surface. The company says the resulting vibration removes water and particulate contamination without mechanical wiping, targeting optics on drones, naval equipment and surveillance systems. DIANA describes a nanoscale transducer that vibrates the inside of the sensor surface. Numeric power, size, interface, window/coating compatibility and operating-temperature limits were not recovered, so broad application claims remain subject to host-specific integration and testing.

These describe the reviewed application scope, not confirmed deployments, released requirements or procurement eligibility.
Evidence of maturity
ClearDrop calls its device market ready. Official records establish i-Lab recognition and 2026 DIANA/accelerator participation; a historical 2023 TRL 8 target is not an attained rating, and no named military acceptance is established.
Commercial availability
Integration enquiries are offered through the official site. Model-specific pricing, delivery lead times, production capacity and qualified host configurations remain unestablished in the reviewed public material.

DIANA describes a nanoscale acoustic transducer vibrating the inside of a sensor surface to remove water, salt or debris without disrupting the sensor itself.
In 2023 the project anticipated 2024 fundraising to reach TRL 8 and prepare industrialization. This does not establish attained TRL 8 today or a current five-person team.
NATO DIANA lists ClearDrop (France) in its 2026 Maritime Operations cohort for acoustic surface-wave cleaning to keep optics operational in all weather.
