Next-generation night and thermal vision
Applied in sectors
Theon Sensors is the Greek reference manufacturer for tactical night vision and thermography systems. Two product lines define their portfolio: NYX, the image intensification night vision goggle family with proprietary GaAs Gen3 tubes, and Thermis, the long-range uncooled thermal sensor family. Theon's structural advantage over equivalent American manufacturers (L3Harris, Elbit) is regulatory: as a European manufacturer certified by NSPA/NATO, their products are not subject to ITAR (International Traffic in Arms Regulations) from the US State Department — eliminating the need for a DDTC license for third-country military procurement and reducing the purchase process from 18-24 months to 3-6 months.
The NYX line ranges from compact infantry monoculars to binoculars with laser rangefinder and digital compass for long-range operations. Theon's proprietary GaAs Gen3 tubes achieve figure of merit (FOM) >2000, equivalent to top-tier American systems, with spectral sensitivity to 1,100 nm — capturing the full NIR spectrum without active illuminator. STANAG 4805 compatibility allows mounting on any NATO-standard PICATINNY/WEAVER rail without adapters. The Thermis line produces uncooled LWIR sensors (microbolometer 640×480 at 17 μm) with human presence detection range exceeding 1,500 m in total darkness and with zero self-emission.

Our team can prepare a technical proposal tailored to your operational requirements.
The difference between image intensification and thermography is tactical: NYX goggles depend on photoelectrons — requiring at least starlight to operate — while Thermis detects thermal infrared radiation emitted by any object above 0 K, even in absolute darkness and through smoke or light fog. The NYX + Thermis combination covers all tactical night vision scenarios: Thermis as a long-range search sensor and presence detector, NYX as a short-range navigation and identification system where image resolution is critical for ROE (Rules of Engagement).
In Peru, priority applications are FFAA nighttime patrols in the VRAEM where NYX Gen3 goggles enable movement in dense jungle without active illumination, Navy riverine interdiction operations with Thermis mounted on patrol vessels for lightless boat detection, and surveillance of northern (Ecuador) and southern (Chile/Bolivia) borders with long-range Thermis at fixed positions. The absence of ITAR enables direct procurement by MINDEF without an American intermediary and without risk of re-export sanctions.
