Thermis Thermal Camera
Technical specifications
Technical overview
The Thermis is Theon Sensors' handheld thermal camera for tactical observation in conditions where conventional night vision is insufficient: fog, smoke, dense vegetation, and static camouflage. Unlike NVG systems that amplify visible and near-infrared light, thermal detects the long-wave infrared radiation emitted by body heat — making camouflage, vegetation, and complete darkness irrelevant as limiting factors.
The 384×288 pixel uncooled VOx (Vanadium Oxide) detector with 17 µm pitch requires no cryogenic cooling time: the Thermis is operational in less than 5 seconds from power-on, versus 3-5 minutes for cooled detector systems. The NETD <40 mK thermal sensitivity allows detecting temperature differences of less than one-tenth of a degree, sufficient to identify recent footprints in the ground or detect camouflaged machinery by its residual thermal signature hours after it has stopped.
