Claim Text:
1. An indicia reading apparatus comprising: a housing; a laser diode assembly; a scanning mechanism for scanning a laser beam in a scan pattern across a target substrate; a lens assembly for adjusting a waist distance of a laser beam canned by the scanning mechanism; an adjustable aperture assembly positioned between the laser diode assembly and the lens assembly, the adjustable aperture assembly adjusting a beam diameter of emitted laser light; wherein the indicia reading apparatus is operative to output image data representing reflected light; wherein the indicia reading apparatus is operative to process image data output by the indicia reading apparatus for attempting to decode decodable indicia; a first configuration in which the adjustable aperture assembly is set to a first aperture assembly setting and the lens assembly is set to a first best focus distance setting; a second configuration in which the adjustable aperture assembly is set to a second aperture assembly setting and the lens assembly is set to a second best focus distance setting, the second aperture assembly setting being a larger diameter aperture assembly setting than the first aperture assembly setting, and wherein the second best focus distance setting is a best focus distance setting longer than the first best focus distance setting; wherein the indicia reading apparatus is operative to output first image data representing reflected laser light reflected from a target substrate with the first configuration active and is further operative to output second image data representing reflected light reflected from the target substrate with the second configuration active; wherein the apparatus is operative to attempt to decode decodable indicia utilizing the first image data and the second image data.
