Distance & Spot size
As the distance (D) from the object increases, the spot size (S) of the area measured by the unit
becomes larger. The relationship between distance and spot size for each unit is listed below.
The distance to target / size of IR focal spot ratio is 12:1. With a distance of 12 cm to the target,
•the size of the IR focal spot is thus 1 cm.
Note:
Field of View: Make sure that the target is larger than the unit’s spot size. The smaller the target,
the closer you should be to it. When accuracy is critical, make sure the target is at least twice as
large as the spot size.
