[1] WD: The distance between the front end of the mechanics and the object.
[2] F#: The real F-number of a lens when used.
[3] DOF (Depth of Field) evaluation formula for telecentric lenses: DOF(mm)=F#×P×k/β2;
P: Sensor pixel size (5.5μm used here)
β: Lens magnification
k: The parameter based on application (measurement, k=0.015; defect detection, k=0.008; 0.015 used here)
At the borders of DOF, the image can be still used for measurement. But only half of the nominal DOF should be used to get a sharp image
