Abstract
The optical image reader is versatile since it can be assembled for use in a variety of reader applications, such as an ultra high definition reader, a high definition reader, a standard reader and an ultra long range reader. In addition to a housing enclosing an image sensor, an adjustable objective lens assembly for focusing an image of a target on the image sensor and a light source for illuminating and/or targeting the target, the reader includes a light shaping optical element array comprising optical elements assembled together as an integral unit and adapted to be fixed to the housing for shaping and directing light on the target. The optical elements are mounted on a panel, which is adapted to be fixed to the reader housing either permanently, or releasably to permit replacement of the panel on the housing. The method of assembling the image reader comprises the steps of selecting a light shaping optical element array from the variety of optical element arrays for the specific application, adjusting the objective lens assembly for optimum focal length for the specific application, and fixing the light shaping optical element array panel to the image reader housing. The present invention is further directed to a kit for an imaging system. The kit for an imaging system comprises an image reader mounted in a housing and one or more light shaping optical element array panels, each adapted to be releasably attached to the image reader housing.
