9-7 Focus
To adjust the focus, turn the lens focus adjuster clockwise or counter-clockwise. When the
target comes into focus, it shows a sharper image. When the target moves out of focus, the
thermal image becomes blurry.
Correct focus is important in all imaging applications. Correct focus makes sure that the
infrared energy is correctly directed onto the pixels of the detector. Without the correct
focus, the thermal image can be blurry, and the radiometric data will be inaccurate. Out-of-
focus infrared images are frequently unusable or of little value.
9-9 Zoom
The imager offers 1-32x continuous zoom functions.
•
Press the Zoom Out button and the image will zoom out 10%. Press and hold for
continuous zooming.
•
Press the Zoom In and image zooms in 10%. Press and hold for continuous zooming.
When zoomed in or zoomed out, the zoom factor displays in the upper status bar.
9-8 Non-uniformity Correction (NUC)
Non-uniformity correction (NUC) is used to compensate for the non-uniformity of detector
pixels or other optical interference. A common need for NUC correction is to reduce excess
noise in an image caused by rapid changes in ambient temperature within an environment.
The imager has two modes for correcting, Manual and Auto Mode. In Manual Mode, push the
Power button and the imager will correct itself. In Auto Mode, the imager can correct itself
automatically while imaging.
When the device is performing a correction the user will hear a click and the image may clear
of some noise grain as the device makes its adjustment.
