SE55 Decode Distances

The table below lists the typical 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 photographic quality barcode at 18° tilt pitch angle under 20 fcd ambient illumination.
Measurement is taken straight from the face of the scan engine's exit window to the surface of the barcode.
