Laser Decode Ranges
The decode ranges provide the decode ranges for barcodes of specified densities. Figure A-2 shows the laser
decode ranges and Table A-4 on page A-7 lists the scan ranges for the 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.
