Focus is the single most important thing to ensure when conducting an infrared inspection, because improper focus can lead to incorrect temperature measurements that could result in wrong decisions. Getting crisp images in manual focus takes time and careful attention, and passive autofocus systems may only capture the near-field target, which may not be the desired target, such as the fence in the example images on this slide. LaserSharp® Auto Focus uses a laser distance meter to calculate and display the distance to the target, then the focus meter immediately adjusts the focus.
