Proper image focus is still one of the most important aspects of performing an infrared inspection. A clear image not only allows for optimal problem diagnosis, but it is also critical to accurate temperature measurement.

Clear focus is not difficult to achieve if you follow a few simple steps:

  • Get as close as safely possible to your target.
  • Take time to carefully focus for optimum clarity. This may take some practice if you have a motorized focus mechanism.
  • Ascertain that your target is stationary.
  • Only shoot from a stable platform. If imaging from a motor vehicle, it may be desirable to shut off the engine to avoid vibration.

Be sure your imager is steady as you capture the image. Gently push the store button rather than punching it. If using a handheld imager, consider using a tripod or monopod to help stabilize your imager.

Once you’ve stored an image, recall and check for clarity. If the results are less than perfect, start over. In addition to greater accuracy, capturing clear images makes it easier to convey information to the end user and/or the person who will eventually perform corrective actions.

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