DISTANCE & DIMENSIONS OF THE LASER BEAM

Hand in hand with the increase of distance (D) between the thermometer and the object from which

the temperature measurement is desired, the diameter of the laser beam (S) or the area measured

becomes larger. The relationship between distance and dimensions of the laser beam is indicated

as follows for the different thermometer models. The focal point is 914mm (36”). The laser beam

dimensions

correspond to 90% of energy emitted.
