摘要： Described is a scanner system and method for imaging an object (e.g., a data symbol, a bar code) which includes an illumination system, a chromatically aberrant lens system and an imaging sensor. The illumination system generates light of first and second wavelengths. The lens system has a first focal distance for the first wavelength light and a second focal distance for the second wavelength light. The sensor receives, via the lens system, light reflected from an object to be imaged. The sensor generates an image of the object by assembling first wavelength light focused thereon when a distance of the object from the lens system is the first focal distance and second wavelength light focused thereon when the distance of the object from the lens system is the second focal distance.
