Claim Text:
1. A light sensing device comprising: a substrate having a surface; a photodetector disposed over the surface of the substrate, the photodetector configured to detect light and to provide a signal in response thereto; an optical baffle extending from the surface to a display screen, the optical baffle configured to at least substantially prevent transmission of optical crosstalk to the photodetector; a casing having an exterior surface and an interior surface, the casing at least partially disposed over the substrate and the photodetector, the casing defining a lens receiving aperture, the lens receiving aperture positioned over the photodetector; and a lens having an exterior surface co-planar with the exterior surface of the casing and an interior surface extending beyond a plane defined by the interior surface of the casing, the lens disposed within the lens receiving aperture, the lens configured to focus light incident upon the lens and to pass the focused light to the photodetector.
