Wide Angle Lenses

Using a standard lens to perform infrared inspections at close distances can be particularly difficult. This situation is quite common when inspecting motor control centers and some types of mechanical equipment.

If you must image from a near distance, you may not be able to compare your target to an adjacent reference. For larger targets you may be able to image only a portion of the target.

Wide angle lenses increase an imagers visual field of view allowing a thermographer to image a wider target area without having to move farther from the target. Wide angle lenses are available for most imagers in multipliers of either 2x wide or 3x wide. Spot measurement size will increase proportionately to the width multiplier for the lens.

If you are taking temperatures, be sure that your wide angle lens has been calibrated for your imager.

Imager operation is one of the many topics covered in all Infraspection Level I training courses. For more information on our Distance Learning Program or our open enrollment classes, visit us online at infraspection.com or call us at 609-239-4788.
