If the imager is not focused, the image quality will be poor and temperature
measurements will not be accurate.
Rotating the lens in a clockwise direction (from front view) focuses the imager at
longer distances up to infinity. Rotating the lens in the opposite direction focuses
the imager at shorter distances down to a minimum of 30 cm.
Rotate the lens until the image has the best definition, and has the sharpest contrast
at object edges.
Focused
54°C measured.
Not focused
46°C measured.
