Laser Decode Ranges
The decode ranges provide the decode ranges for barcodes of specified densities.
decode ranges and
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.
Note: Typical performance at 73˚ F (23˚ C)
on high quality symbols.
