Handheld Cameras - Thermal Imaging

Handheld thermal imaging cameras are portable infrared detection instruments that detect and display the heat radiation emitted by objects, surfaces, and living subjects within their field of view, producing a visual image based on temperature differences rather than visible light. Unlike standard optical cameras that require illumination, thermal cameras function in complete darkness, through smoke, light fog, and camouflage cover, making them valuable for security, surveillance, search and rescue, and building inspection applications where visible light is absent or insufficient.

The core sensing element is a microbolometer focal plane array (FPA) that absorbs longwave infrared radiation in the 7.5 to 14 µm spectral range and converts it into a measurable resistance change for each pixel. Detector resolutions across professional handheld thermal cameras range from 160 x 120 pixels on compact entry-level units to 640 x 480 pixels and above on high-performance models, with higher resolution producing finer temperature discrimination and target detail at greater distances. Thermal sensitivity, expressed as NETD, falls between 25mK and 50mK on professional-grade units, indicating the minimum temperature difference the camera can distinguish between adjacent areas.

Display output is rendered on an integrated LCD screen in selectable color palettes including white-hot, black-hot, rainbow, and iron-bow, each optimized for different detection and analysis scenarios.
