Interpretation aid for the field of view diagram
Using the diagram, you can determine the following data for each device type:
•
The maximum working distance for a selected code resolution
•
The dimensions of the field of view that is available for this distance

Given (in red):
•
Code resolution 2D code 7: 1.0 mm
•
Focal length of lens 8: 9.6 mm
Read off (in green):
•
Maximum working distance 9: approx. 920 mm
•
Field of view ß: approx. 640 mm x approx. 510 mm
Both axes of the diagrams must be interpreted linearly.
