Thermal imaging is one of the most powerful technologies
ever developed to enhance human vision.

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.


FLIR ONE is lightweight, easy
to connect and easy to use.

You’ll explore the world around you in ways you never thought possible, with no additional cords, cases, devices or screens necessary. Pop it onto your iPhone5 or 5s, and take it with you wherever you go. A new world of vision in the palm of your hand.

Why does my FLIR ONE have two cameras?

MSX® Technology

Raw thermal images are beautiful, however, they don't provide too much physical detail. So the FLIR ONE blends both images using MSX Technology, providing physical detail to the raw thermal reading. With MSX Technology, the FLIR ONE captures what nothing else can.

Thermal Image



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, and it's positioned to equip a new generation of mobile and handheld devices with unprecedented thermal imaging capabilities.


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.


Weighs just 3.9 ounces, and displays directly
on your phone’s screen.


Snaps easily onto your iPhone5 or 5s like a protective case.
