Spot Size to Distance
The measured surface area can represent a cone emanating out from the
sensor. The further the distance to the surface, the larger the area that will
influence temperature measurements. It is important that when it safe to do
so, get as close as possible to the target, using the single laser to define the
center of an imaginary circle. This will increase the accuracy of the displayed
temperature. Also, make measurements at 90 degrees to the surface as
angular measurements are less accurate. (Reference diagram below)
