Bar code scanning system with offset optical axes

A scan module and an optical system such as for a bar code scanner wherein the optical system has an axis of outgoing (illumination) light offset from the axis of collected light, arranged to limit the dynamic range of the collected light and thus the dynamic range within which the bar code scanner...

description	A scan module and an optical system such as for a bar code scanner wherein the optical system has an axis of outgoing (illumination) light offset from the axis of collected light, arranged to limit the dynamic range of the collected light and thus the dynamic range within which the bar code scanner detector and signal processor must function. Preferably, the outgoing axis and the collection lens axis are substantially parallel.
