Infrared wide angle lens, 4335361, Fluke
This lens gives you a wider field of view when working in confined spaces, allowing you to see a larger target object from a shorter distance. So you can see a whole row of switchgear or more components through one IR window in a confined space. Because you can see a much larger area at once, you can look at the entire side of a building without having to move too far away, or check rooftops faster than with a traditional lens.
Save yourself the hassle of sending your camera in for calibration with the lens! Smart Lenses let you easily attach to the compatible camera and then immediately take pictures.
