    摘要: The present disclosure provides systems and techniques for directing light into one or more light beams which converge into an aggregate beam. In certain example embodiments, the present disclosure provides a reflector having one or more reflective curved surfaces for reflecting and focusing light from one or more light emitting diodes (LEDs) into one or more light beams, which make up an aggregate light beam. In certain example embodiments, the reflective curved surfaces are paraboloid surfaces.

    摘要: Embodiments of the present invention comprise an indicia reading terminal including a focus element that extends the range of focus distances at which the indicia reading terminal can decode decodable indicia. In one embodiment, the focus element comprises a variable form element and a variable position element, the combination of which causes an image distance that can change in accordance with a separation distance between these two elements. The focus element can comprise an actuator, e.g., a piezoelectric actuator, which can be coupled to the variable position element in a manner that can cause the variable position element to deform the variable form element, and in one example, the deformation changes the focal length of the variable form element.
