Relationship between camera distance and read field size
The following images show the relationship between the camera distance and the resulting read field for
the individual optics models of the code reader. The camera distance is the path from the front edge of the
code reader to the code.
Please note that the actual reading distances are also influenced by factors such as labeling
material, printing quality, reading angle, printing contrast etc., and may thus deviate from the
reading distances specified here.
