Reading field curves
Notice!
Please notice that the real reading fields are also influenced by factors such as labeling
material, printing quality, scanning angle, printing contrast etc., and may thus deviate from
the reading fields specified here.
The zero position of the reading distance always refers the front edge of the housing of the
beam exit and is shown in figure 5.5 for the two housing types of the BCL 558
