The following figure shows the focus distance of a reader equipped with an LT-
51x illuminator:
Figure 100 - Focus distance = α + β
The best results for this illuminator are obtained when α is approx. 13 mm
(0.5’’). β measures 75 mm, therefore the focus distance in this case equals 88
mm.
CAUTION
The minimum and maximum DPM application distance is limited by both the lighting
system working distance and the reader focus distance.
For example, the minimum application distance is limited by the reader minimum
focus distance (25 mm for liquid lens models). The maximum application distance is
limited by the smaller of the illuminator maximum working distance or the lens max-
imum focus distance. See also “Global FOV Diagrams” on page 94.
