Field of View and Reading Distances
The following maps show the field of view of the DataMan 360 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.
Note
: Due to tolerances, ranges can vary by +/- 5 % from unit to unit.
Reading Distance and Field of View (DataMan 360 Readers with a 10.3 mm
Liquid Lens)
The map below shows the field of view (FoV) of the DataMan 360 readers with a 10.3 mm lens (with or without a liquid
lens).
The FoV values are shown as follows:
l
outer: DM362, DM363
l
inner: DM360
The reading distances for the DM360 and DM362 readers are the same. DM363 features a higher resolution and more
pixels in about the same sensor size.
The following table shows the FoV widths in mm at various distances.
