Table 11-2: Long Range Laser Decode Distances
Advanced Long Range Laser
The Apex PDT equipped with the Advanced Long Range Laser
decodes the symbols as shown in Figure 11-3. The values shown
are typical. The associated table lists the typical and guaranteed
distances for selected bar code densities. The minimum element
width (or “symbol density”) is the width in mils of the narrowest
element (bar or space) in the symbol. The maximum usable length
of a symbol at any given range is shown below.
