ABSTRACT:
An illumination beam director for use with a diagnostic instrument having an optical lens system including a camera aperture for observing along an optical viewing axis passing through the camera aperture, and an illuminator including an illuminator aperture for projecting illumination along a first illumination axis passing through the illumination aperture. The light beam director includes a pair of opposed redirecting surfaces which receive the light from the illuminator along a first illumination axis and redirect the light onto a second illumination axis, wherein the second illumination axis is closer to the optical axis than is the first illumination axis to overcome shadowing effects on the viewing axis.
