Optical Charts
The following optical charts show the diameter of the measuring spot in dependence on the distance between measuring object and sensing head.
The spot size refers to
90 % of the radiation energy
. The distance is always measured from the front edge of the sensing head
.
D = Distance from front of the sensing head to the object
S = Spot size
•
The size of the measuring object and the optical resolution of the infrared thermometer determine
the maximum distance between sensing head and measuring object.
•
In order to prevent measuring errors the object should fill out the field of view of the optics
completely.
•
Consequently, the spot should at all times have at least the same size like the object or should be
smaller than that.
