Abstract:
1. An arrangement for generating a substantially uniform distributed illumination pattern of light on and along a symbol to be read by image capture, comprising: an imaging system including a solid-state imager having an array of image sensors and an imaging lens assembly for capturing return light over a field of view from the symbol along an imaging axis, and for projecting the captured return light onto the array; an illuminating light assembly including an illumination light source for emitting illumination light at an acute angle of inclination relative to the imaging axis, and an optical component including a first lens portion for intercepting, bending and aligning the emitted illumination light to generate the pattern in a scan direction along the symbol, and a second lens portion for collimating the aligned illumination light to generate the pattern in a transverse direction generally perpendicular to the scan direction; and wherein the light source includes a pair of light emitting diodes (LEDs) surface mounted on a printed circuit board (PCB) tilted at said acute angle of inclination relative to the imaging axis, and wherein the imager is also surface mounted on the PCB.
