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
focal point for each unit is 914mm (36”). The spot sizes indicate 90% encircled energy.

Note:
Accuracy:
Given at 18 to 28°C (64 to 82°F), less than 80 % RH.
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.
