Abstract
Embodiments of the disclosure relate generally to imaging devices and indicia reading devices. An imaging apparatus comprises an image sensor, an optical window positioned in front of the image sensor and a light source enclosing a perimeter of the optical window such that an illumination cone of the light source overlaps a portion of a near field of view cone of the imaging apparatus. The portion of the near field of view cone extends from a surface of the optical window to a threshold distance from the optical window. The light source is configured to produce a first illumination along a first direction extending towards a scene to be imaged.
