Claim:
1. An optical sensor comprising: a transparent substrate having a surface; at least one light emitter directly mounted to the surface of the transparent substrate, the at least one light emitter configured to emit light; a photodetector assembly directly mounted to the surface of the transparent substrate, the photodetector assembly configured to detect light and provide a signal in response thereto; a polymeric encapsulation structure disposed over the surface of the transparent substrate that at least substantially encapsulates the at least one light emitter and the photodetector assembly, the polymeric encapsulation structure comprising at least one of scattering elements or absorbing elements, the polymeric encapsulation structure having a surface distal to the surface of the transparent substrate; and a plurality of solder bumps disposed over the surface of the transparent substrate, respective solder bumps of the plurality of solder bumps extending beyond a plane that is co-planar with the surface of the polymeric encapsulation structure.
