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:
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.
