Normally, our vision is limited to a very small portion of the electromagnetic spectrum. Thermal energy has a much longer wavelength than visible light. So long, in fact, that the human eye can't even see it, just like we can't see radio waves.
With thermal imaging, the portion of the spectrum we perceive is dramatically expanded, helping us "see" heat. Visible light doesn't affect the thermal world, so you can see equally well in highly lit and totally dark environments.
The FLIR ONE™ thermal camera allows us to see things the naked eye could never perceive on its own.
This is the camera that allows the FLIR ONE to take a thermal reading. Smaller than a dime, it's the most compact long-wave infrared sensor available.
Every time you capture a thermal reading with the FLIR ONE, you are also taking a standard picture. This picture will provide physical detail to the raw thermal reading.
