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 sensor housing/ CF-lens holder/ air purge.
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.
