D:S (focus point) = 75:1/ 16mm@1200mm               D:S (focus point) = 62:1/ 1mm@62mm 
D:S (far field) = 36:1                    D:S (far field) = 4:1 
 
The measured area of the object (spot size) 
depends on the distance. For a correct 
measurement the spot size should have at least 
the same size like the object or should be 
smaller than that at all times. 
D = Distance from front of the unit to the object 
S = Spotsize
