| 1. A reader for electro-optically reading a target, comprising:
a) a housing having a window; and
b) a solid-state imager in the housing and including an array of image sensors for capturing target light through the window
from the target over a field of view;
c) an illuminator in the housing for directing illumination light to and through the window to illuminate the target during
reading, a portion of the illumination light incident on the window being reflected therefrom into the housing away from the
window; and
d) the window being configured as a non-planar, curved optical element for collecting, redirecting and focusing the reflected
portion of the illumination light to a focal point spaced away from the imager to enhance reader performance.
