OptiArray and OptiBarrier deliver reliable, early acoustic warning for naval and coastal security.
OptiArray is a compact, towed optical hydrophone array designed for submarines and surface vessels. It delivers anti-submarine detection with minimal drag, low power demand, and complete immunity to electromagnetic interference. The system supplies high-fidelity, real-time acoustic data and is set to be integrated into the Royal Netherlands Navy’s new Orka-class submarines.
OptiBarrier extends this technology to fixed defense. Its modular seabed sensors create wide-area acoustic fences that deliver 24/7, over-the-horizon threat detection around harbors, pipelines, and critical infrastructure.
Both systems are fully optical, require no electrical power at the sensor, and are engineered for long-term reliability in harsh marine conditions.
Founded in 2011 in Amsterdam, Optics11 designs advanced fiber-optic sensing systems that give defense operators earlier warning and more time to act.
