Illumination lens for an optical code reader |
摘要 |
An optical code reader of the imager type is disclosed, having an illumination lens (15) associated with a light source. In a first direction (X), a main face (16) of the lens (15) has a plurality of elementary regions (17), each having a slope with respect to the optical axis (A-A) of the reader that is individually calculated so that said elementary region (17) 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. |
