Lens Choice for Looking Through IR Windows

by Gary Orlove

More and more organizations are installing IR windows or sight glasses in their electrical equipment so inspections can be made with an infrared camera.

The advantages are obvious: worker safety is improved as thermographers and electricians don't have to open live electrical cabinets, and inspection times can be reduced.

However, what lens choice is the best to use with your infrared camera to provide adequate resolution, and yet see as much of the electrical equipment as possible?

Here are three images that were taken at a power plant looking at an ISO phase buss. The buss is only about a foot away and is taken looking through an infrared window (crystal type).

As you can plainly see, the 90° lens is clearly the way to go.  It provides enough detail for analysis, yet extends your field of view by a huge amount.

This video makes me proud I was able to contribute to the shuttle thermal imaging program; and makes me sad that it is ending.

It has an outstanding collection of visible and infrared imagery; superbly edited with a great score - just about the best combination of the Science of Imagery Analysis and the Art of “Film” Editing.
