Infrared 101
Infrared can be described as light we can’t see. This is because infrared lightwaves have longer wavelengths than those of visible light. Visible lightwaves we can process with human sight, but infrared lightwaves need to be detected and processed with the advanced technology found in infrared cameras. An infrared camera processes infrared lightwaves, unlike our eyes, and produces a thermal (heat) image of an object from the infrared world. For all objects which emit a heat signature that is measurable we can use an infrared camera to capture its thermal image. This thermal image can then be interpreted by an infrared thermographer either quantitatively or qualitatively. The infrared camera also stores the infrared images for documentation in reporting software. And, this is where you benefit by being able to make decisions based on what you can see in infrared!
Other inspection methods fall short when compared. For a more informed, and involved, explanation of infrared theory go to these two ‘great’ sites :

Benefits of Infrared
Here are the important aspects for you, or your company, to consider in when having an infrared evaluation: infrared is the use of an advanced technology that allows you to ‘see’ the thermal image of an object and measure its temperature for analysis which traditional inspection methods will not give you infrared gives you visual documentation of a thermal image to use for comparison to later inspections, for corrective actions, or in prioritizing faults for later repairs and considerations infrared gives you the reporting and documentation capabilities for workmanship and warranty issues, and for use in possible litigation cases infrared is competitively priced!
infrared saves you time ....it finds problems quickly and it’s a non-destructive inspection application infrared saves you money ....by avoiding business downtime and assuring efficiency in equipment and systems operation
