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.
