摘要：

An illumination apparatus for an imaging-based bar code reader having a field of view defined by an imaging system of the bar code reader directed toward a target bar code. The illumination apparatus includes: a collector cup comprising a compound parabolic concentrator and defining a longitudinal axis; an illumination source positioned to direct illumination toward a first end of the collector cup, the collector cup directing illumination from the illumination source toward a second end of the collector cup; a first lens array positioned at the second end of the collector cup orthogonal to the collector cup longitudinal axis to receive and focus illumination from the collector cup and a second lens array orthogonal to the collector cup longitudinal axis receiving focused illumination from the first lens array. The lens arrays combining to focus illumination from the collector cup into an illumination pattern.
