Field of View and Reading Distances
The following maps show the field of view of the DataMan 370 series readers. Reading distance values are also
provided for 1-D and 2-D example code distances.
For the C-mount (or other non-Cognex) and S-Mount lenses, the focal length of the lens, focus setting, and aperture
setting determine the field of view and reading distance.
The ruler shows the reading distance range. The grid with the FOV cone shows horizontal and vertical FOV values
above the arrows.
Note
: Due to tolerances, ranges can vary by +/- 5 % from unit to unit.
