Thermal imaging is based on heat. Energy given off by heat is actually part of the upper infrared light spectrum. The energy waves can be collected and focused by the right equipment to create a visible image, even when something is not visible to the naked eye.
Visible and infrared (IR) wavelengths are part of the continuous electromagnetic spectrum. Within the IR part of the spectrum, there is a long-wave infrared (LWIR) spectrum. There, objects emit energy even when visible light is not present.
- Can highlight people, animals, and objects
- Works in both daylight and darkness
- Can see through haze and smoke
- Isn’t blinded by bright light
Different temperatures are rendered as different levels of brightness (shades of gray) in the visible thermal image. Living things generate their own heat, but even inanimate objects (like rocks) give off the heat they have absorbed from the sun and other sources.
EOTech holographic weapon sights with thermal imaging technology have been extensively tested and proven to operate in even the most extreme conditions. HWS are temperature proof by design, with...
