Optical Diagram 

The optical diagrams indicate the target spot diameter at any given distance 
between the target object and the sensing head. 
All  target  spot  sizes  indicated  in  the  optical  diagrams  are  based  on  90% 
energy.

Calculating the Target Spot Size 

To calculate the target spot size from two known points within an 
optical diagram the following formula can be used: 

 

Sx = unknown diameter of target spot 
Sn = smallest known diameter of target spot 
Sf = greatest known diameter of target spot 
Dx = distance to unknown target spot 
D

n

 = distance to smaller known target spot 

D

f

 = distance to greater known target spot
