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.
