• Simply put, infrared imaging technology makes a picture using infrared light (heat) instead of visible light.
• More technically, infrared (IR) light is electromagnetic radiation with longer wavelengths than those of visible light. Although the infrared spectrum begins at the Near Infrared wavelengths (.75 micrometers) and ends at, quite logically, the Far Infrared wavelengths,  at A1 infrared, our imagers "see" in the Long Wavelength infrared range (typically 8-15 micrometers).
• This allows us to see and quantify variations in the surface temperatures of an object in real time and without contact or destruction. These temperature differences can help identify possible problems or deficiencies.
• Infrared also allows us to "see" in darkness and through atmospheric conditions (smoke, fog and steam) which helps make infrared suitable for a wide variety of applications.

The infrared imager makes images in several different pallets. In this image, the white areas are the hottest, black areas are coldest.

Same ducky, different pallet. Here black  areas are hottest.

This pallet is called rainbow. Note how it brings out the "reflection" of the ducky on the surface of the table.

This is Ozzy, a domestic long hair. Using the scale bar at right, we can see how the shorter hair on his face, ears and paws allow more of his body heat to escape. It also shows his nose is one of the coldest things in the image, while his eyes are the warmest.

These images show a failing transformer connection. Identifying problems such as this not only prevents catastophic failure, but also leads to lower energy costs.
