An optical code reader of the imager type is disclosed, having an illumination lens associated with a light source. In a first direction, a main face of the lens has a plurality of elementary regions, each having a slope with respect to the optical axis of the reader that is individually calculated so that said elementary region deviates the light fraction coming from the light source and incident thereon towards a specific elementary region of the illumination pattern. It is thus possible to create any desired irradiance profile.

Abstract

An optical code reader of the imager type is disclosed, having an illumination lens associated with a light source. In a first direction, a main face of the lens has a plurality of elementary regions, each having a slope with respect to the optical axis of the reader that is individually calculated so that said elementary region deviates the light fraction coming from the light source and incident thereon towards a specific elementary region of the illumination pattern. It is thus possible to create any desired irradiance profile.
