Fig. 4 Table with examples (thermoIMAGER TIM 40) showing what spot sizes and pixel sizes will be reached in which distance
HFOV: Horizontal enlargement of the total measuring field at object level
VFOV: Vertical enlargement of the total measuring field at object level
IFOV: Size of the single pixel at object level
1) The accuracy of measurement can be outside of the specifications for distances below the defined minimum distance.
