VB34 model with reflex mirror
VB34-2500-OM, resolution: 0,20 mm (8 mils)
The diagram shows a global reading zone, which is practically the sum of all the
possible focus positions, and the reading zone, which results for the VB34-2500-OM
from a focus position of 600 mm and a barcode density of 0,20 mm (8 mils).
The values for the maximum and the minimum distances are found in the radial
distance curves in Figure 8.22.
