IR Field of View
Ensure that the desired target is larger than the spot size. As the distance from an object increases, the
spot size of the area measured by the meter becomes larger. The meter’s field of view ratio is 8:1,
meaning that if the meter is 8 inches (cm) from the target, the diameter (spot) of the object under test
must be at least 1 inch (cm). Refer below to the field of view diagram.

WARNING: Do not directly view or direct the laser pointer at an eye.
Low power visible lasers do
not normally present a hazard, but may present some potential for hazard if viewed directly for
extended periods of time.
