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 resolution
•
The dimensions of the field of view that is available for this distance
a: f = 9.6 mm
b: f = 17.1 mm

Given (in red):
•
Resolution 5: approx. 0.5mm/px
•
Focal length of lens 6: 9.6mm
Read off (in green):
•
Maximum working distance 7: approx. 930mm
•
Field of view 8: approx. 640mm x approx. 510mm
Both axes of the diagrams must be interpreted linearly.
