8.5 Calculating the C-mount Lens and the Size of the Field
of View for Data Matrix Codes at a Given Distance
The following table shows the suitable lens and the corresponding field of view for
the sensor head 6GF2 002-8CB (resolution 640 * 480) for a data matrix code of the
size 44 mm x 44 mm and a dot size of 1 mm.
