The following figure shows the focus distance of a reader equipped with an LT-51x illu-
minator:
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.

Figure 113 - Focus distance = α + β
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 maximum focus distance. See also "Global
FOV Diagrams" on page 93.
