Abstract
A scanner for reading barcode symbologies having a focusing illuminating source. The scanner uses a coherent light source for illuminating the coded symbol during a scan and a detector for collecting the reflected light energy from the coded symbol. Both the illuminating and collecting devices include lenses which are in variable spacial relationship with each other. The scanner varies the relationship between the light source and associated focusing lens to provide the narrowest focused beam at the barcode location.
